The Boolean Search

Boolean searching is a technique that permits you to narrow or broaden your search using specific connectors to define the relationship between your search terms. Let’s delve deeper into the intricacies of Westlaw and LexisNexis's Boolean search:

Common Proximity Connectors:

• AND: Narrows down results to documents containing both terms.Example: contract AND breach
• OR: Expands the search to documents with either or both terms.Example: judge OR magistrate
• Quotation Marks (" "): Denotes an exact phrase search.Example: "intellectual property"
• Parentheses ( ): Groups synonyms or related terms.Example: (theft OR burglary OR robbery)
• /s: Searches for terms within the same sentence.Example: liability /s damages
• Pre/s or +s: Ensures the first term appears before the second within the same sentence.Example: plaintiff +s rights
• /n: Dictates that search terms appear within 'n' words of each other.Example: fraud /5 misrepresentation
• Pre/n or +n: Ensures the first term precedes the second within 'n' words.Example: patent +3 infringement

Differences in Search Processing: Lexis vs. Westlaw

LexisNexis:

• Prioritizes phrases in quotation marks.
• Processes /s and /p connectors without searching for punctuations for sentences or paragraphs.
• Processes connectors within parentheses before those outside.

Westlaw:

• Treats spaces as OR, unless between words in quotation marks.
• Searches for punctuations to determine the beginning and ending of sentences and paragraphs with /s and /p connectors.

Special Tip:

For both platforms:

• If connectors are all numerical, the search runs left to right.
• For mixed numerical and grammatical connectors, numerical ones process first, followed by /S before /P.
