------------------------------------------
Summary: Allow WildcardQuery and RegexpQuery to also use
auto-prefix terms
Key: LUCENE-5967
URL: https://issues.apache.org/jira/browse/LUCENE-5967
Project: Lucene - Core
Issue Type: Improvement
Reporter: Michael McCandless
In LUCENE-5879, we added auto-prefix terms, where the terms dict finds good
prefix terms to index, so that at search time PrefixQuery and TermRangeQuery
can visit far fewer terms than the full set.
WildcardQuery and RegexpQuery will only make use of auto-prefix terms if it's
"effectively" a PrefixQuery (e.g. WildcardQuery("foo*")), but we could fix them
so they could also use auto-prefix terms for other cases (e.g. foo?b*) though
in practice it's less likely to have an impact I think.
