What is the purpose of the "Use expressions" checkbox in saved searches?

The "Use expressions" checkbox in saved searches is primarily intended to enable the use of advanced logical operators, such as "NOT" and "OR." When this option is checked, it allows users to construct more complex search criteria by combining multiple conditions using these operators. This flexibility is crucial for users who want to refine their data retrieval beyond simple equality or inequality checks.

By enabling advanced logical operators, users can formulate intricate queries that can either narrow or broaden the scope of the data returned in their searches, depending on the requirements. This capability is essential for creating dynamic and tailored search results that meet specific business needs.

The other choices do not accurately describe the function of the "Use expressions" checkbox. For instance, while summary types are useful in saved searches, they relate more to data aggregation rather than logical processing. Similarly, custom KPI filters involve different settings that are not directly tied to the use of logical expressions. The option to disable certain fields from the search is also unrelated to this checkbox, as it pertains to field selection rather than expression evaluation.
