Otis Gospodnetic commented on LUCENE-524:
-----------------------------------------

Based on the description, yes.  Doesn't this also sound a lot like that old 
Mark H's issue that you commented on earlier?


> Current implementation of fuzzy and wildcard queries inappropriately 
> implemented as Boolean query rewrites

> 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
