------------------------------------------
Summary: Optimize BlockTree's Terms.intersect a bit for "very
finite" automata
Key: LUCENE-6548
URL: https://issues.apache.org/jira/browse/LUCENE-6548
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 5.3, Trunk
I've been digging into why BlockTree's Terms.intersect impl is slower for a
"very finite" union-of-terms test over random IDs (LUCENE-3893) and I found a
few performance improvements that at least for that one use case gets a ~11%
speedup.
