PREFACE
This manual is designed to
instruct you in doing legal research on CaseLawResearch.com. Part 1 gives the basics
of searching on CaseLawResearch.com and an overview of the product's searching
philosophy. Part 2 will walk you through conducting your first search. Part 3
introduces advanced searching strategies. Part 4 is a sample research project
that incorporates the whole process.
Assumptions
This documentation assumes
that you are already comfortable with the basic functionality of a web browser
(e.g., NCSA Mosaic, Internet Explorer, Netscape, etc.)
Conventions
To help you quickly
distinguish different types of information, this documentation adheres to the
following conventions for notation and visual cues: Italics are used to
emphasize a word or phrase, or to indicate a variable expression (e.g., dbname)
Initial Caps are used for the names of keys (e.g., Enter, Alt+F, Ctrl+P) and
interface elements (e.g., Search Results Window, Navigate Menu, Back button.)
ALL CAPS are used for the name of a path, directory or file, such as C:\TEXTDB\*.SRC. Bold words are used to represent the contents of a text file,
program listings or sample queries.

Manual Part 1:
Welcome to
CaseLawResearch.com and
Search Basics
Thank you for learning more about case law
research provided by CaseLawResearch.com. If
you've never conducted electronic searching, you will find it easy to learn and
surprisingly efficient. If you have prior experience with Westlaw or LEXIS,
that experience will be helpful, but remember, CaseLawResearch.com is a different
product. Even though each of these services can provide you with court cases,
each has a unique way of doing it. That will affect your strategy and search
construction.
Electronic Searching Strategy
Searching is a process, not
an event. This should be your mantra when using CaseLawResearch.com. Searching a
library is not about spending time and mental energy formulating the
"golden query" that retrieves your desired information in a single
stroke. In practice, good online searching involves formulating a succession of
queries until you are satisfied with the results. As you view results from one
search, you will come across additional leads that you did not identify in your
original search. You can incorporate these new terms into your existing query
or create a new one. After each query, evaluate its success by asking:
·
Did I find what I was
looking for?
·
What better information
could still be out there?
·
How can I refine my
query to find better information?
Issuing multiple queries can
be frustrating or rewarding, depending on how long it takes you to identify the
key material you need to answer your research problem.
Full-Text Libraries and Documents
Defined
A full-text library is a
collection of related whole documents assembled into a single searchable unit.
The individual documents can be massive or minuscule, but they should bear some
relation to each other (e.g., court opinions issued from the same
jurisdiction). A full-text library is composed of smaller units called
documents. When you search a database, you will retrieve documents that contain
information that matches your query request.
Virtual Library: Searching Multiple
Libraries
Your query can search in
multiple jurisdictions at once; this is known as a virtual library. Our system
organizes the information this way to make it easier to find for users. This
way, you don't have to know precisely which exact jurisdiction an opinion was
handed down from in order to find it. Documents retrieved from different
jurisdictions are combined into one Results List, but with an abbreviation next
to each one to tell you which jurisdiction the opinion comes from.
Indexing
CaseLawResearch.com, Lexis and
Westlaw all depend on the word as an essential tool to search and retrieve
documents. And, like Lexis and Westlaw, CaseLawResearch.com uses the principle of
word indexing. During the publication process, an indexer goes through every
document and creates an index of every word in every document and also
tabulates how many times each word is used in each document. When you do a
search, you are not really searching through the full-text of the documents;
you are searching the word index of the documents.
Stop Words
As opposed to a
keyword-based system, CaseLawResearch.com uses a full-text retrieval software,
meaning that it indexes every word in a document with the exception of Stop
words. Stop words are those terms that are programmed to be ignored during the
indexing and retrieval processes, in order to prevent the retrieval of
extraneous documents. Generally, a stop word list includes articles, pronouns,
adjectives, adverbs and prepositions ("the", "they",
"very", "not", "of", etc.) that are most common
words in the English language. Using stop words in full-text searching is vital
in the context of Relevance Ranking; as described below.
Relevance Ranking
The most powerful weapon in
the searcher's arsenal is Relevance Ranking. Simply put, relevance ranking
lists a set of retrieved documents so that the documents most likely to be
relevant are shown to you first. Remember, Relevance Ranking is not an
indication of legal relevance. Relevance Ranking arranges documents based on
the mathematical measurement of similarity between your query and the content
of each record. What determines the likelihood of relevance? An analysis of the
database is performed using a combination of the following indicators:
·
Breadth of Match -
Documents containing more of the various query terms are weighted more
relevant.
·
Inverse Document
Frequency - Documents containing terms which occur less frequently in the
entire database are weighted more relevant.
·
Frequency - Documents
with a higher occurrence of a query term are weighted more relevant.
·
Density - The
comparable length of retrieved documents is calculated to apply a higher
relevancy weight.
In this analysis, stop words
are ignored. This reduces the time spent processing your search and prevents an
artificial boost of relevance to what are actually irrelevant documents, since
"the" would probably retrieve every record in a database.
The researcher receives several benefits from Relevance Ranking. With the ease
of natural language queries and the assistance of Relevance Ranking, you will
find the most relevant documents in the shortest period of time. And, as you
read down the Hit List, once you determine the documents are getting less
applicable, you can stop reading results of this search because you know you
have already viewed the most relevant documents. Finally…you don't have to be a
computer expert who can compose the most complex of queries in order to find
valuable information!

Manual Part 2:
Conducting a Search
When you connect to CaseLawResearch.com to conduct
legal research, click on the Search button from the homepage, then complete the
following steps:
Step 1: Select Jurisdiction to Search
Step 2: Design a Query
Step 3: Submit the Query/View the Results
Step 4: View a Document
Step 1: Select Jurisdiction to Search
To begin, you must select a category. For example, if you select “Federal
Circuits” as your category, after you press Submit you have the opportunity to
select the specific circuits to include in the search. You select or deselect a
jurisdiction by clicking on the associated box. In CaseLawResearch.com, you are not
limited to searching in one jurisdiction at a time, nor are you limited to a
grouping of jurisdictions.
Step 2: Design a Query
A query is a word or string of words you want to find in retrieved documents.
When designing a query, you should think about the words a court would use when
discussing the issue you are researching. When you have determined the words
you want to search for, you can design a query based on those words connected
with Boolean connectors (AND, NOT, OR, etc). Alternatively, you can search for a phrase without
using Boolean connectors. More on phrases later.
BOOLEAN SEARCHING
A Boolean search requires the researcher to incorporate operators into the
query. A search operator is one or more characters that instructs the search
engine on how words should be related in retrieved documents. An operator can
work at word-level, where it applies to a single query term, or at query level,
where its presence affects the processing of the entire query. When you use a
search operator in conjunction with a stop word, the operator is ignored.
By way of background, the Boolean search was named after George Boole, a
mathematician of the nineteenth century. Boolean logic is a commonly used
algebraic form where all values are reduced to either a true or false
convention. The three Boolean search operators are: AND, OR, NOT. Here are
examples of these three operators:
medical
AND malpractice
searches for all documents
that contain both the search terms that the operator AND separates. All
documents that are found by this search will have both the word “medical” and
the word “malpractice” in them. In George’s world this meant that in order for
the statement to be true, the documents had to contain both words.
medical
OR malpractice
searches for all documents
that contain either of the search terms separated by the operator OR. All
documents that are found by this search will have either the word “medical” or
the word “malpractice” in them.
medical
AND NOT malpractice
searches for all documents
that contain the search term(s) before the NOT operator, but not after it. All
documents that are found by this search will contain the word “medical” but not
the word “malpractice.”
medical
AND NOT legal malpractice
also searches for all
documents that contain the search term(s) before the NOT operator, but not
after it. All documents that are found by this search will contain the word
"medical" but not the phrase "legal malpractice." In this
example, the search engine first looks for documents in which the word
"medical" occurs. Then, because the default operator is ADJ, the
search engine looks for instances in those documents where the word
'legal" is adjacent to the word "malpractice" and discards them
retaining only those documents in which the word "medical" is present
without the phrase "legal malpractice."
CAUTION: It is not advisable to start your search query with the NOT operator.
For example, if you start with the query “NOT malpractice” the search engine
will retrieve ALL documents that do not contain the word “malpractice.” This
is not usually a desirable result. If you choose to start your search query with
the NOT operator, you can minimize this effect by specifying a short date range.
However, the best practice is to avoid using the NOT operator at the beginning
of a search query. Using the "AND NOT" technique described above will
give you better results.
OTHER SEARCH OPERATORS
The default operator is ADJ (adjacent). Therefore, if no operator is specified,
the search engine will look for the words in the search query occurring
immediately adjacent to one another. ADJ is unidirectional, from left to right,
e.g., the query "medical malpractice" will result in documents where
"medical" is immediately to the left of "malpractice" but
not "malpractice medical."
There are still other operators you can use to help you get the results you
need. You can consult our Operator
Grid for a concise list of operators. If you have search experience with
Westlaw or LEXIS, you may find the Operator
Comparison Grid to be helpful, too.
PHRASES and NATURAL LANGUAGE SEARCHES
Because the default operator on CaseLawResearch.com is ADJ, you can search for a
phrase by simply entering the phrase in the search query box. For example, to
search for “negligent infliction of emotional distress” just type that phrase
in the search query box. The search engine will automatically search for those
words immediately adjacent to one another in the same order they are typed.
A Natural Language query is one that is expressed using normal conversational
syntax; that is, the query is presented as if making a spoken or written
request to another person. However, because the default operator on CaseLawResearch.com is
ADJ, a natural language search will not obtain satisfactory
results unless you only enter a search for words that you would expect to
appear immediately adjacent to one another in the opinions you hope to
retrieve.
Once you have designed your query type the words and search operators in the
box labeled: Enter Your Search.
OTHER SEARCH OPTIONS
You have the option to specify a date range; use
this format: 01/01/1999. As a final option, you can select the Number of
Results (documents) to retrieve (25, 50, 100, or 200) by using the pull-down
menu. The default is set at 50.
Step 3:
Submit the Query/View the
Results
Once you have entered a query, click on Submit to launch a search for relevant
documents. Most searches process within 30 seconds. It's probably simpler to
just wait and try again, but should you wish to interrupt a search in progress,
you should talk to your system administrator.
THE SEARCH RESULTS SCREEN
When the search engine
finishes processing your search query, the site displays the Search Results
Window (a.k.a. “The Results List”). Appearing at the top of the results list
is a statement indicating the number of documents your requested.
If your search retrieves no documents, a message will appear above the
"Enter Your Search" box that reads "Your search returned no
results." Edit your search text or your options and try again.
Some other tips:
Step 4:
View the Document
To view a document, click on its name in the Results List. The screen will
display the document. Your search terms will be highlighted in the document; use
your browser’s scroll bar to move around within the opinion to find the
highlighted search terms. Alternatively, you can use your browser’s Find
function (CTRL+F3) to jump to a particular search word within the document. To
close a document and return to the Results List, click on the "View
Results" button at the top of your screen.
While examining the retrieved documents, you may learn of additional relevant
search terms or find that your search query was too broad and retrieved
irrelevant documents. To try again, click on the "New Search" button
and then enter your search query again with any changes you wish and hit
"Submit" again. Writing down a query might be helpful if you need to
find a specific document again.
Research
Manual Part 3:
Advanced Search Techniques
This section explains three
additional tools that help you retrieve relevant documents with increased
precision: advanced operators, wild cards, and shortcut searching. As you
incorporate these tools, you will want to understand the processing rules and
the ramifications of nesting that are associated with these techniques.
Advanced Operators
In addition to the Boolean
operators you were introduced to in Part 2, there are additional operators
which let you do even more precise types of searching. Using these operators,
you will find documents where your search words appear only in the exact
relationship to each other. Stop words and punctuation do not count as words in
the stated range.
Proximity Operator
w/n:
The first proximity operator allows you to specify the number of words between
your search terms. This operator is bi-directional; that is, it will retrieve
documents where the second word appears on either side of the first word by the
stated number. For example, to find documents about "deficit
spending", your search may look like this:
deficit w/5 spending
This search would retrieve documents in which the word "spending"
either precedes or follows the word "deficit" by one to five words.
When designating the number of words remember that Stop Words count; therefore,
you should use a number that will allow for any Stop Words that might be
included in the phrase. Example: "negligent and intentional spoliation of
evidence" counts as six (6) words.
Wild Cards
Wild Cards can be very useful if you are unsure of the spelling of a word or if the word is commonly misspelled. The single character wild card operator, a question mark (?), substitutes for a single character, while the character string wild card operator, an asterisk (*), represents a string of unknown characters.
Here are examples of Wild
Cards, how to use them and what they retrieve:
Search Word with Wild Card
Retrieves
medic*
medics, medical, medicine, medicate, medically, medication
*ane
bane, lane, crane, plane, profane, insane
m?n
man, men
m???
mean, moon
m*n
man, men, mean, maroon, Manhattan
run+
run, runs, running, rerun
judg?ment
judgement, judgment
Note: You cannot use wild
card operators to represent numeric characters (e.g., 19??).
Note: You can combine both
wild card operators within a single query word, e.g., ?ffect*, for results such
as, effecting, effective, affects, etc.
Processing Rules
When processing search
queries, CaseLawResearch.com evaluates some types of operators before others. If you
formulate queries in which different operator types are combined, you should
understand the order in which they will be processed. The search operators are
processed in the following order:
Proximity,
Adjacent, Near (processed in order from left to right)
NOT
AND
OR
If you want to override the
processing rules, you can use parentheses as scope of operation delimiters to
change the order in which operators are processed, just as you did in an 8th
grade algebraic expression.
Nesting
If you use one set of parentheses inside
another to reorder the processing, you have done what is called nesting,
wherein one operation becomes a subset of another. The nested (internal)
operation is evaluated before the one that contains it. If you want to retrieve
documents discussing negligence or
assumption of the risk related to jaywalking, your search may look
like this:
(negligen* or (assum* w/5 risk)) and jaywalk*
Search Operator Grid
You can consult our Operator Grid for a concise list of operators. If you have search experience with Westlaw or LEXIS, you may find the Operator Comparison Grid to be helpful, too.

Manual Part 4:
Putting It All Together: A Sample Research Problem
Okay, so now you have an
understanding of each component part of performing legal research on CaseLawResearch.com. Now, how do you actually put a search together in real life? The
number one challenge of an electronic legal researcher is to anticipate how a
judge will characterize an issue in a legal opinion and what terms of art are
used in this area of law.
To get the feel for the
whole research process, we’ve included a research problem that is designed to
take you through all of the steps in conducting legal research on CaseLawResearch.com.
Suppose you have a client
relay these facts to you:
The
client’s son lives in a house owned by the client and, though his son is an
adult, the son pays no rent. The son was arrested and charged with illegal drug
trafficking (sale of marijuana) allegedly using the house as his base of
operations. Later, the U.S. government instituted civil forfeiture proceedings
and seized the house. At this point the client produces a notice of forfeiture
under 21 U.S.C. Section 881(a)(7). The client believes this forfeiture is
unconstitutional since a) his son was convicted of the crime and seizure of the
house seems like double jeopardy; and b) the house didn't belong to the son to
begin with.
To begin your research, access the www.CaseLawResearch.com and click on Cases then Search Case Law.
To begin your research, choose a library. Select the Federal Circuit Courts library from the list. This library allows a search in any or all federal circuit courts, including the District of Columbia. On the Search Query Page, click the box for any circuits you want to search; you can select one or several.
Now, enter your search in the Search Query box. To begin
the research, let’s focus on the seizure. Read through the text in the form to
see if you can find any hints as to special words they use to talk about this.
To find cases dealing with any type of property seized as a result of the
federal civil forfeiture law due to trafficking marijuana or any type of drug,
your search may look like this:
(civil forfeiture) AND (drugs OR marijuana)
What you hope the above search will find are documents where the word
"civil" is in front of (i.e., adjacent to) the word
"forfeiture"; and where the word "drugs" or
"marijuana" occur in the same document.
Type in a Date Range (format: MM/DD/YYYY) within the past two or three
years to ensure you get all of the "recent" opinions. Since we will be
happy with finding 50 cases on this issue, we won’t change the Number of
Results. Click on "Submit".
When the search is finished processing, the site displays a results list with
several documents in it. Remember that the documents are arranged with the
highest relevance score at the top. What's actually going on is that the search
engine has "looked" at the statistical occurrences of your search
terms in each found document and ranked them based on its ranking algorithm. To
view any of the listed documents, click on the name and they will load up on the
screen.
Now that you’ve studied the approach, give CaseLawResearch.com a try with your own
research project. If you run into any brick walls, contact a research customer
service representative via e-mail info@CaseLawResearch.com or give
Customer Service a call for assistance.
Good Luck!
