------------------------------
Resolution: Fixed
I'm going to say its time to close this with all of the changes/improvements
that have gone on here. Most of the issues brought up are addressed in a
different manner. Further changes should be brought up in a new issue.

> implemented as Boolean query rewrites

> Key: LUCENE-524
> URL: https://issues.apache.org/jira/browse/LUCENE-524
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Search
> Affects Versions: 1.9
> Reporter: Randy Puttick
> Priority: Minor
> Attachments: MultiTermQuery.java, MultiTermScorer.java
>
>
> The implementation of MultiTermQuery in terms of BooleanQuery introduces
> several problems:
> 1) Collisions with maximum clause limit on boolean queries which throws an
> exception. This is most problematic because it is difficult to ascertain in
> advance how many terms a fuzzy query or wildcard query might involve.
> 2) The boolean disjunctive scoring is not appropriate for either fuzzy or
> wildcard queries. In effect the score is divided by the number of terms in
> the query which has nothing to do with the relevancy of the results.
> 3) Performance of disjunctive boolean queries for large term sets is quite
> sub-optimal
