Bruno Roustant updated LUCENE-9237:
-----------------------------------
Description:
New version of TermsEnum intersect for UniformSplit. It is 75% more efficient
than the previous version for FuzzyQuery.
Compared to BlockTree IntersectTermsEnum:
- It is still slower for FuzzyQuery (-37%) but it is faster than the previous
version (which was -65%).
- It is roughly same speed for WildcardQuery (-5%).
- It is slightly faster for PrefixQuery (+5%). Sometimes benchmarks show more
improvement (I've seen up to +17% a fourth of the time).
