How do I search?

Searching in DISCO is similar to other database tools you may have used in the past, such as Westlaw and/or Lexis Nexis. Like these legal research databases, Disco uses Boolean search operators. We recommend you use this guide as a resource to reference these operators as well as the different search terms syntax available for use to filter or expand your search results.
