A more detailed history of Spotlight

Since writing A brief history of local search, I have come across numerous patents awarded to Apple and its engineers for the innovations that have led to Spotlight. This more detailed account of the origins and history of Spotlight uses those primary sources to reconstruct as much as I can at present.

AppleSearch released, and bundled in Workgroup Servers. This was based on a client-server system running over AppleShare networks. September’s release of System Software 7.5 introduced a local app Find File, written by Bill Monk.

Sherlock was released in Mac OS 8.5. This adopted a similar architecture to AppleSearch, using a local service that maintained indexes of file metadata and content, and a client app that passed queries to it. This included remote search of the web through plug-ins working with web search engines, as they became available.

Early patent applications were filed by Apple’s leading engineers who were working on Sherlock, including US Patent 6,466,901 B1 filed 30 November 1998 by Wayne Loofbourrow and David Cásseres, for a Multi-language document search and retrieval system.
