Subject [jira] Commented: (LUCENE-1951) wildcardquery rewrite improvements
Date Thu, 08 Oct 2009 14:46:31 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1951?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12763507#action_12763507

Robert Muir commented on LUCENE-1951:
-------------------------------------

think there would be objection to making this proposed SingleTermEnum public?

I would like to use it in LUCENE-1606 (contrib) to have consistency there as well.

> wildcardquery has logic to rewrite to termquery if there is no wildcard character, but
> * it needs to pass along the boost if it does this
> * if the user asked for a 'constant score' rewriteMethod, it should rewrite to a constant
score query for consistency.
> additionally, if the query is really a prefixquery, it would be nice to rewrite to prefix
query.
> both will enumerate the same number of terms, but prefixquery has a simpler comparison
function.
