“There is a theory which states that if ever for any reason anyone discovers what exactly the Universe is for and why it is here it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another that states that this has already happened.” -- Douglas Adams (British comic Writer, 1952-2001)

LexisNexis is a system of databases with a powerful search engine. As with most current subscription databases, LexisNexis provides a menu-driven search option, which can help the beginning searcher. For the more advanced searcher, it also provides a sophisticated search syntax for more efficient searching of the databases.
To make most effective use of the advanced search syntax, your first contact should be your corporate or academic librarian. If your organization does not employ such a person, your next stop should be your LexisNexis representative.
For the die hard do it yourselfer, there are other resources. Here are a couple of them, with search examples to provide some hints on how to construct your own search statements.
One of the best LexisNexis cheats I have found is the one produced by Thomas Cooper Library, University of South Carolina (http://www.sc.edu/library/libguides/lggeneral/lexisnexis.pdf). Hint: The first step is to choose the appropriate LexisNexis database. The second step is to use the search operators described below to construct the best search statement.

Basics of Searching Lexis Nexis Academic Universe (2009)
Thomas Cooper Library, University of South Carolina
To search LEXIS-NEXIS Academic Universe effectively, you need to understand the organization of the database and the operators or connectors used in constructing searches
NEWS
General News US and international
Today's News News articles updated through the day
U.S. News Newspaper, wire and transcript articles from a state and selected articles about each state
World News News from U.S. and international sources
Wires Wire service reports
Transcripts Television & radio news broadcasts
Arts & Sports Reviews, entertainment and sports news
Campus Chronicle of Higher Education and student newspapers
Non-English Language News Spanish, French, Dutch, Italian & German
BUSINESS Retrieve full text company news and financial information
LEGAL Search full text federal, state, and international legal materials
RESEARCH Legal News Law Reviews Codes and regulations
MEDICAL Find full text and abstracted medical and health information
REFERENCE Search general reference sources
LEXIS-NEXIS Academic Universe is a full text database and because of that you may find using the / connectors more effective than and. The following is a list of connectors and some other options for constructing searches. All of these options are only available in Guided searches (not Quick search).
atleast# restricts results to documents containing the term so many number of times the terms goes inside parentheses atleast5(terrorism)
/n The letter n stands for a number from 1 to 255. /n does not specify a word order
Example: gas /5 price - - finds gas within five or fewer words of price, regardless of which word appears first
/p Words must be in the same paragraph
/s Words must be in the same sentence
Note: The /p connector cannot be combined with the /n connector
and Both words appear anywhere in the same document or Link synonyms, alternative forms of expression and acronyms
pre/n Requires both words to appear in the document. The first word must precede the second word by n number of words. Use this connector when a different word order would change the meaning.
Example: cable pre/3 television will find cable television instead of television cable
and not Excludes documents that contain the word or phrase following it. Use this connector with caution because it can exclude relevant documents. Always use this connector at the end of your search.
Example: doctor and not malpractice - - finds the word doctor anywhere in the document, but the word malpractice cannot appear anywhere in the document
* Use the asterisk (*) to replace a letter or letters in a word. You can use more than one asterisk in a word and you can use it anywhere except as the first letter.
Examples: bernst**n finds either ei or ie spelling of the name bank*** will pick up banker and banking, but not bankrupt or bankruptcy
! Use the exclamation mark (!) to replace an infinite number of letters following a word root.
Examples: acqui! finds variations of the word acquire (acquired, acquiring, acquisitions) book! finds book or bookkeeper, but will not find book-keeper or book keeper because those are read as two separate words
singular LEXIS-NEXIS automatically searches singular, regular plural and plural possessive
and endings for search words. For example, a search on the term company will find company,
plural companies, and company’s.
When you want only the plural or singular form, use the plural or singular command singular (company) plural (aids)
caps word(s) must have one or more capital letters. Useful when researching names.
allcaps word(s) must have all capital letters. Helpful when searching acronyms.
allcaps(plural(aids))
segment When viewing a document, any header (or segment) with a bold label is searchable even if you do not find in as a pull down option from the search box.
Segments will vary across different portions of the Lexis/Nexis Academic database.
Example: To view the front page of a newspaper, it will depend how a specific newspaper names and numbers the sections. This might even change over time with the same newspaper.
section(a and pg 1) ……. Full Text
section(1 and page 1) …. Full Text
Length is another segment in many parts of Lexis Nexis. If you wanted to find longer newspaper articles that part of your search would look like this:
length>1500 ……. Full Text
In the Transcripts part of Lexis/Nexis, show is a segment.
show(60 minutes or dateline or 20/20) ……. Full Text

The strength of LexisNexis lies in the areas of law and news. Since LexisNexis is a subscription based resource, if your organization does not provide access to LexisNexis, you are kind of stuck. However, LexisNexis does provide non-subscription access to a portion of its legal database through Lexis Web beta (http://www.lexisweb.com/)
Below are the results of a search on “dibenzothiophene.” Why, you might wonder, would you want to search a legal database for something like “dibenzothiophene?” Good question. In your capacity as a technology researcher, you might not. But what if you wanted to know what lawsuits involving “dibenzothiophene” might have occurred? In that case, LexisNexis might help.
