Viktor Lofgren 6efc0f21fe (index) Clean up data model
The change set cleans up the data model for the term-level data.  This used to contain a bunch of fields with document-level metadata.  This data-duplication means a larger memory footprint and worse memory locality.

The ranking code is also modified to not accept SearchResultKeywordScores, but rather CompiledQueryLong and CqDataInts containing only the term metadata and the frequency information needed for ranking.  This is again an effort to improve memory locality.

Search Service

This service handles search traffic and is the service you're most directly interacting with when visiting search.marginalia.nu.

It interprets a "human" query and translates it into a request that gets passed into to the index service, which finds related documents, which this service then ranks and returns to the user.

Central classes

  • SearchService receives requests and delegates to the appropriate services.

  • CommandEvaluator interprets a user query and acts upon it, dealing with special operations like browse: or site:.

  • SearchQueryIndexService passes a parsed search query to the index service, and then decorates the search results so that they can be rendered.
