16. A system for searching data, comprising: a processor configured to: use a searchable index to determine which, if any, data objects from current production data and a set of backup data are responsive to a search query, wherein a data object in the set of backup data corresponds to a version of the production data as the production data existed when a backup operation was performed; in the event that a plurality of data objects is responsive to the search query: determine from the plurality of data objects responsive to the search query a subset of related data objects that are related to each other; determine from the subset of related data objects a first data object that comprises a version of one or more other data objects included in the subset of related data objects; and generate for the search query a search result that includes data that indicates version relationships between the first data object and the one or more other data objects included in the subset of related data objects; and in the event no data object is responsive to the search query, generate said search result to indicate that no data object is responsive to the search query; an interface device configured to present the search result; and a memory coupled to the processor and configured to provide the searchable index.

The system as recited in claim 16 , wherein determining from the plurality of data objects responsive to the search query the subset of related data objects comprises determining if the first data object comprises a subsequent version of one or more other data objects of the plurality of data objects.
