1. porter stemmer offers method to NOT do lowercasing, however to use this we must convert to runes first ourself, so we did this 2. now we can invoke the version that skips lowercasing, we already do this ourselves before stemming through separate filter due to the fact that the stemmer modifies the runes in place we have no way to know if there were changes, thus we must always encode back into the term byte slice added unit test which catches the problem found NOTE this uses analysis.BuildTermFromRunes so perf gain is only visible with other PR also merged future gains are possible if we udpate the stemmer to let us know if changes were made, thus skipping re-encoding to []byte when no changes were actually made |
