This change simplifies and removes the DisjunctionSearcher.currentID tracking, and instead utilizes the the matching/matchingIdxs slices for tracking the required information. As the core of the optimization, the previous code used two loop passses to compare the internal ID's to the currentID field. This commit instead optimizes to have a single pass to both compare the internalID's and to also maintain the matching/matchingIdxs arrays. On my dev box, using a bleve-query benchmark on a wiki dataset, with query-string of "text:afternoon text:coffee", the previous code had throughput of 958qps, and this commit has 1174qps. |
