------------------------------------------
Summary: Can PrefixQuery subclass AutomatonQuery?
Key: LUCENE-6367
URL: https://issues.apache.org/jira/browse/LUCENE-6367
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: Trunk, 5.1
Spinoff/blocker for LUCENE-5879.
It seems like PrefixQuery should "simply" be an AutomatonQuery rather than
specializing its own TermsEnum ... with maybe some performance improvements to
ByteRunAutomaton.run to short-circuit once it's in a "sink state",
AutomatonTermsEnum could be just as fast as PrefixTermsEnum.
If we can do this it will make LUCENE-5879 simpler.
