Using LexisNexis

In the early days of conducting legal research online, must was said on how it should be done.  Law firms paid for these services based on the time the researcher was using the system, and not by a flat rate subscription.  It was fast (if you knew what you were doing) but it was expensive.  Today, these advanced technologies have been put in the reach of most university students.  The search technologies have come a long way, and the method of conducting legal research is not that different from using familiar search tools such as Google.

As anyone who has every used Google can attest to, one of the biggest problems you run into is finding the terms you searched for hundreds, thousands, or even millions of times.  The hard part is often finding exactly what you want to find.  Using legal research databases is often like this.  One of the most important skills you can develop in using LexisNexis is narrowing down your search to find just a handful of sources that you must manually sort through.

When you are searching for something very specific, such as a particular case, be very specific with your search.  For example, if you know that you are looking for Miranda v. Arizona, do not search just “Miranda.”  You will be better off still if you can search by an exact citation.  Knowing that Miranda is cited as 384 US 436 will result in one and only one search result.  This is accomplished by using the find a case feature.

Most internet users are accustomed to natural language searches.  This is searching for what you want by asking the search engine a question.  Another type of search is known as a Boolean search.  Boolean searches were common in the early days of the internet, but gave way as natural searches become more and more accurate and user-friendly.  Because of the specificity required, Boolean searches can still be useful in legal research.

Finding LexisNexis

If you are using computers on the network of an institution that subscribes to LexisNexis, you should be authenticated automatically.  If you are on a home or other network, you will most likely need to navigate to LexisNexis through your Library’s portal.  If you cannot figure this out the first time, speak with a Librarian.  There may be instructions on your library’s website as well.  The features that you will find may vary according to your library’s subscription.  There are different levels of subscriptions.  The URL for LexisNexis Academic is  This will take you to the “Academic Search” screen.  Using the search box that you will find on this page is not a very efficient way to begin legal research.  It is more efficient to navigate to the type of legal materials that you want to search for specifically.  To do this, select “Search by Content Type” (which is located just above the search box) and select the type of material that you want to search (or browse).

Finding Cases

The easiest way to find a particular court case on LexisNexis is to use the “Look Up A Legal Case” feature.  This is located at the bottom of the “Academic Search” screen.  When you click on this, a dialog box will open, with fields to search by citation, by the parties to the case, and by legal topic.  Searching by citation is the best way to focus your search to a specific case quickly.  Citation searches, however, are very sensitive to formatting issues.  Make sure that the volume and page numbers are correct, and that you are using the proper reporter abbreviation.

Finding Codes

The procedure for finding codes in LexisNexis is similar to a search for cases.  Under the “Search By Content Type” menu, there are different options for state statutes and federal statutes.  Simply select the one that you are looking for.  When you have selected “State Statutes and Regulations,” the advanced options menu allows you to pick one or more states.  You can also select whether you want to search the statutory code, the administrative code, or the constitution.  The default is to search all types of codes and regulations for all states.  This will result in an unwieldy number of results.

Advanced Searches

LexisNexis allows the user to conduct an Advanced Search with the “Build Your Own Segmented Search” tool.  This tool allows the user to narrow down searches in a very specific way.  A document segment or section is an element within a document, such as the “Date.”  These sections identify certain specific elements of a document.  Segment searches are useful when the researcher needs to narrow a search to be very specific.  This sort of searching is frequently referred to as “fielded” or “faceted” searching.  Rather of searching all of the text in a document, you may find it useful to only search within a segment of the document for more precise results.

Another feature of the advanced search options is the use of what LexisNexis calls connector buttons.  These allow the segment terms discussed above to be connected with Boolean expressions.  The following connectors are available:

AND: Returns documents that contain one search term and another search term.
OR: Returns documents that contain either one search term or another.
AND NOT: Returns documents that contain one search term, but not the other.
w/5: Returns documents that contain one search term within five words of another search term.
w/p: Returns documents that contain one search term within the same paragraph as another.
