A method of searching data, comprising: processing backup data (202, 204) and production data (214, 216) to provide to an indexer content data usable to generate a searchable index of the backup data and the production data, wherein the backup data includes versions of data objects backed up from the production data; generating the searchable index including by: determining a set of related data objects from the content data, wherein a first data object is related to a second data object if the first data object has ever shared a common file name and/or path or another identifier with the second data object or another data object related to the second data object; and in response to the determination of the set of related data objects, storing data associating the set of related data objects together in the searchable index; receiving a search query comprising one or more keywords (314, 502); using the searchable index to determine a plurality of data objects comprising the backup data and the production data that are responsive to the search query, wherein the plurality of data objects includes a first data object included in the set of related data objects; generating a search result set that includes an indication that the first data object is related to a second data object included in the set of related data objects, based at least in part on the data associating the set of related data objects together stored in the searchable index (316,402,404); and displaying search results comprising the search result set in a manner that indicates visually that the first data object comprises a different version of the second data object based at least in part on the indication that the first data object is related to the second data object (406,504). processing backup data (202, 204) and production data (214, 216) to provide to an indexer content data usable to generate a searchable index of the backup data and the production data, wherein the backup data includes versions of data objects backed up from the production data; generating the searchable index including by: determining a set of related data objects from the content data, wherein a first data object is related to a second data object if the first data object has ever shared a common file name and/or path or another identifier with the second data object or another data object related to the second data object; and in response to the determination of the set of related data objects, storing data associating the set of related data objects together in the searchable index; determining a set of related data objects from the content data, wherein a first data object is related to a second data object if the first data object has ever shared a common file name and/or path or another identifier with the second data object or another data object related to the second data object; and in response to the determination of the set of related data objects, storing data associating the set of related data objects together in the searchable index; receiving a search query comprising one or more keywords (314, 502); using the searchable index to determine a plurality of data objects comprising the backup data and the production data that are responsive to the search query, wherein the plurality of data objects includes a first data object included in the set of related data objects; generating a search result set that includes an indication that the first data object is related to a second data object included in the set of related data objects, based at least in part on the data associating the set of related data objects together stored in the searchable index (316,402,404); and displaying search results comprising the search result set in a manner that indicates visually that the first data object comprises a different version of the second data object based at least in part on the indication that the first data object is related to the second data object (406,504).
