Abstract: Methods and apparatuses for storing, organizing and searching files stored in a storage device. Backup files may be stored in snapshot-dependent and/or snapshot-independent paths. The backup files may be stored with additional attributes that can be used for searching and/or indexing purposes.

Abstract: Systems and methods for processing an inverted index are described. Multiple queries against the same inverted index are merged into merged query of unique nodes. The unique nodes are used to create a unified document set from which query result iteration is performed to eliminate redundancies and/or inefficiencies in processing the multiple queries separately. The merged query result is separated into the results for each of the multiple queries and returned to the respective originators of the queries. The unified document set can be limited to postings lists found in a single pulse of the inverted index to improve performance. Index updates can be applied to the merged query result to provide efficient and up to date query results.
