US Patent 9002872 Techniques for parallel processing of directory searches

Techniques for parallel processing of directory searches are provided. A directory search is received on a multicore or multiprocessor architecture machine. At least two threads processing on different cores or processors of the machine handle different aspects of the directory search. A first thread identifies matches in the directory for the search and serially populates the matches to search results. The second thread serially and in parallel grabs the matches in the search results and filters some out and modifies other ones of them to complete processing on the search. The search results are then returned to an initial requester making the initial search.
