Research as a Process: Terms & Connectors

Basic Connectors on Westlaw and Lexis

Search Tips

  1. Both systems default to a natural language search if connectors are not included between terms, but all will also permit terms and connectors searching.
  2. The table below shows connectors in lower case except for when all caps must be used for the connector to work properly. 
  3. In Westlaw, a space is interpreted as n OR connector. In Lexis, how a space is interpreted depends on the other connectors that are present in the search. To be on the safe side, it is best to type out the AND/OR connectors and to enclose phrases in quotes in all three systems, that way you don't have to remember the variations.
  4.  When you enter the singular form of a noun, Lexis and Westlaw automatically search for the singular, plural, and possessive forms of that term (e.g., crime - Lexis and Westlaw also look for crimes). 
  5. If you want to run a terms and connectors search using only the AND/OR connectors in Westlaw, start your search with advanced
