Abstract: A method system and computer having a database management system to apply a user-provided index authored by a programmer, wherein the user-provided index is accepted by the computer and the database management system applies the user-provided index and the user authored index descriptor in database searches. A user may select, generate, and direct the computer to generate, or input an index descriptor, or information used by the computer to populate an index descriptor. The computer may examine the index descriptor in response to receipt or generation of a search query, and determine a relevance of the user-provided index for use in processing the query. The database management system may include a plurality of indexes, and the computer may evaluate the index descriptor to determine a relevance of the user provided index relative to the plurality of indexes. The computer may optionally apply a sequence of indexes in processing a search.
