Terms & Connectors: Fastcase

A guide to Boolean search commands in Westlaw, Lexis+, and Bloomberg Law


Fastcase automatically omits certain common words (e.g., the, it, etc.) from your query. The search runs
more efficiently without these common “noise” words.


At present, Fastcase will accommodate a search up to 500 words long. For purposes of search
length, a Boolean operator counts as a word.
