- TermSearcher has alternate constructor if term is []byte, this can avoid
copying in some cases. TermScorer updated to accept []byte term. Also
removed a few struct fields which were not being used.
- New MultiTermSearcher searches for documents containing any of a list of
terms. Current implementation simply uses DisjunctionSearcher.
- Several other searcher constructors now simply build a list of terms and
then delegate to the MultiTermSearcher
- NewPrefixSearcher
- NewRegexpSearcher
- NewFuzzySearcher
- NewNumericRangeSearcher
- NewGeoBoundingBoxSearcher and NewGeoPointDistanceSearcher make use of
the MultiTermSearcher internally, and follow the pattern of returning
an existing search.Searcher, as opposed to their own wrapping struct.
- Callback filter functions used in NewGeoBoundingBoxSearcher and
NewGeoPointDistanceSearcher have been extracted into separate functions
which makes the code much easier to read.
