Dynamic query hints in LDAP search operations

Abstract:

The present disclosure relates generally to Lightweight Directory Access Protocol (LDAP), and more particularly, to techniques for improving query performance on an LDAP server. One particular technique includes receiving a LDAP query having search criteria, identifying one or more search filters within the search criteria; evaluating one or more mappings for search filter patterns to index query hints based on the identified one or more search filters; identifying one or more query hints based on the evaluation of the one or more mappings; selecting one or more indices based on the one or more query hints; and executing the LDAP query on an LDAP directory using the selected one or more indices.
