The University of Cincinnati Libraries created an amazing guide for building terms and connectors searches in the various legal databases. This guide offers a terms and connectors research strategy and discusses the nuances in each of the databases.
They offer a basic overview and also a side-by-side comparison of the connectors in each of the major legal databases - Bloomberg Law, Lexis Advance, WestlawNext.
There is also promotional information from each of the databases that aids in searching.
Great job, University of Cincinnati Libraries! This is a wonderful, practical guide.
