Which operation is used for creating advanced search queries?

The use of a Boolean search is fundamental for creating advanced search queries because it allows users to combine keywords with operators such as AND, OR, and NOT to refine their search results. This method enables more precise targeting of information by including or excluding specific terms. For example, using the AND operator narrows the search by requiring all specified terms to be present, while the OR operator broadens the search by allowing for any of the specified terms to be included.

While basic search is useful for quick queries, it typically does not offer the same level of detail or control as Boolean searches. Proximity search, on the other hand, focuses on the distance between words in a query but does not provide the same comprehensive capabilities for combining or restricting terms as Boolean search does. Consequently, for users looking to conduct thorough and complex searches within a database or system, the Boolean search operation is the most effective choice.
