What type of searches using key words are often called?

The term "Boolean Searches" refers to a specific method of search that uses Boolean logic to combine keywords with operators such as AND, OR, and NOT. This allows users to refine their search queries for greater precision and relevance in the results generated. By employing these logical operators, a user can construct more complex queries that target specific information, making it a powerful tool for legal research where precision is often paramount.

In contrast, other options have distinct meanings. Natural Language Searches typically allow users to input queries in everyday language, while Keyword Searches focus strictly on individual words without the logical connectors. Text Searches are broader and may refer to searching through any textual data, not necessarily employing specific logical frameworks. Therefore, the recognition of Boolean Searches as the correct term highlights its unique and systematic approach to managing search results effectively.
