>            Priority: Minor

>
> For queries that expand to multiple terms (PrefixQuery, RangeQuery, 
> FuzzyQuery, WildcardQuery), the default now is to rewrite to a BooleanQuery, 
> which scales poorly, and can hit the dreaded TooManyClauses (ungraceful 
> degradation).
> Except for FuzzyQuery (which we should fix with this issue), they all support 
> setConstantScoreRewrite, which scales better.
> In 3.0 we should make constantScoreRewrite the default, and leave an option 
> to turn it off.
> This is a spinoff from LUCENE-998.
