Abstract
A method and apparatus for proxying search requests for a storage system and maintaining a central index for performing the search requests is described herein. An index manager on the storage system may initially produce the central index by examining each file in a file system and update the central index thereafter by examining only those files that have changed since the central index was initially produced or last updated. The index manager may receive a changed file list from a differencing layer configured for comparing snapshots of the file system at different time points to produce changed file lists. A search proxy module may receive search requests in a search protocol and proxy the search requests to a search engine by converting the search requests to another search protocol compatible with the search engine. The search engine may then use the central index for performing the search request.
