Using Search Connectors and Commands

Search connectors are the logic words used to help narrow a search, such as AND, OR, W/n, by defining relationships between your search terms. Search commands provide additional search options, such as ALLCAPS and ATLEAST, which allow you to get more precise results from your search. The following articles provide descriptions and examples for each connector and command.

For information about how multiple connectors work together, see How are Multiple Connectors Processed?

For information on how wildcard characters such as ! and * are used in a search, see Finding Variations of a Word.

Caution:The Search bar located at the top of the Lexis®Library application uses a natural-language system that does not support these connectors. However, the search fields in all other areas of the product do support these connectors.

Priority of Connectors

Previously, by default, connectors were supported according to a specific order (e.g., OR before AND, etc.). Today, that order runs from left to right. Examples follow.

insurance AND claim W/5 definitionThis example enforces the AND connector before the W/5 connector as if the search was formatted.
(insurance AND claim) W/5 definitionIn this example, in order to find the word insurance anywhere in the document together with the word claim within 5 words of the word definition, the search should be formatted as insurance AND (claim W/5 definition).
