and not Connector

Use the and not connector to exclude documents containing specific words or phrases. For example, the following search finds documents containing the word "capital" but not the word "gains":

capital and not gains

In this example, the search finds all documents containing the term "capital" except those that also contain the term "gains".

Using multiple and not connectors

Because of the priority order in which Lexis Advance Pacific evaluates search conectors, if you want to exclude documents containing two or more specific words or phrases, you must precede each of those words or phrases with an and not connector. For example, to find documents containing the word "capital" while excluding documents that contain either the word "gains" or the word "improvements", you must write the search expression as follows:

capital and not gains and not improvements

This search finds all documents containing the term "capital", except those that also contain either "gains" or "investments".

Important: As suggested, because of the priority order in which Lexis Advance Pacific evaluates search connectors, the search expression "capital and not gains or investments" is NOT evaluated to mean "(capital) and not (gains or investments)". Instead, it is evaluated to mean "(capital or investments) and not (gains)". Therefore, to enhance your understanding of how Lexis Advance Pacific will evaluate search expressions containing one or more "and not" connectors, it is often helpful to place the "and not" connectors at the end of the expressions. For more information, see How multiple search connectors are evaluated.
