Abstract

This disclosure provides various embodiments of systems, methods, and software for managing distributed index data. For example, in one embodiment, software for managing distributed index data may identify a query for one or more data objects from a data repository using a generic index, map the query to one of a plurality of logically distributed indices according to at least one rule, and execute the mapped query using the particular distributed index to retrieve the one or more data objects. Each distributed index may be in a disparate index repository that is on a disparate storage device. In some aspects, the one or more rules may include a plurality of business rules, as well as at least one technical rule, which may be stored in a rules repository. In further aspects, an administration view may be presented to a client such that one of the business rules is customized.
