[jira] [Updated] (LUCENE-9237) Faster TermsEnum intersect for
UniformSplit
[ https://issues.apache.org/jira/browse/LUCENE-9237?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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).
