US Patent 11514032 Splitting a query into native query operations and post-processing operations

Techniques for splitting a query into native query operations and post-processing operations are provided. In one embodiment, a user query including a plurality of search parameters is received. Expressions representing the plurality of search parameters in the user query are determined. A first subset and a second subset of the expressions are identified. Each expression of the first subset corresponds to one of a plurality of native query operations executable by a database platform, and each expression of the second subset corresponds to one of a plurality of predefined post-processing operations not executable by the database platform. A database query is generated based on one or more expressions of the first subset, and a post-processing query is generated based on each expression in the second subset. The database query is executed by the database platform, then the post-processing query is executed on the results from database platform.
