A modern text indexing library for go. (this is a mirror of the github repository)

![]() AnalysisResultsToSegmentBase() allows analysis results to be directly converted into a zap-encoded SegmentBase, which can then be introduced onto the root, avoiding the creation of mem.Segment data structures. This leads to some reduction of garbage memory allocations. The grouping and sorting and shaping of the postings list information is taken from the mem.Segment codepaths. The encoding of stored fields reuses functions from zap's merger, which has the largest savings of garbage memory avoidance. And, the encoding of tf/loc chunks, postings & dictionary information also follows the approach used by zap's merger, which also has some savings of garbage memory avoidance. In future changes, the mem.Segment dependencies will be removed from zap, which should result in a smaller codebase. |
