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

![]() On a couple of micro benchmarks on a dev macbook using bleve-query on an index of 50K wikipedia docs, scorch is now in more the same neighborhood of upsidedown/moss... high-freq term search "text:date"... 400 qps - upsidedown/moss 360 qps - scorch before 404 qps - scorch after zero-freq term search "text:mschoch"... 100K qps - upsidedown/moss 55K qps - scorch before 99K qps - scorch after Of note, the scorch index had ~150 *.zap files in it, which likely made made the worker goroutine overhead more costly than for a case with few segments, where goroutine and channel related work appeared relatively prominently in the pprof SVG's. |
