[jira] [Created] (LUCENE-3893) TermsFilter should use
AutomatonQuery
TermsFilter should use AutomatonQuery
-------------------------------------
Key: LUCENE-3893
URL: https://issues.apache.org/jira/browse/LUCENE-3893
Project: Lucene - Java
Issue Type: Improvement
Reporter: Michael McCandless
I think we could see perf gains if TermsFilter sorted the terms, built a minimal automaton, and used TermsEnum.intersect to visit the terms...
This idea came up on the dev list recently.

bq. Dahiwikwukblabla
Daciuk, the name is Jan Daciuk :) Although the same algorithm has been discovered independently by Stoyan Mihov and (I think) Bruce W. Watson.

Thanks! I was on my mobile phone when commenting this and had the names not in mind :-)

---------------------------------------
I already have something like this implemented when Dawid ported the Dahiwikwukblabla Automaton builder to Lucene core. We dont need a separate Filter or Query for that, just use (for the Filter):
new MultiTermQueryWrapperFilter(new AutomatonQuery(unionAutomaton))
To have a backwards-compatible TermsFilter, we can simply do it like PrfeixFilter (subclass MTQWF) and warp the above Automaton.

LUCENE-3832 should also be done for this...
