Uwe Schindler commented on LUCENE-1557:
---------------------------------------
It is almost obsolete. Fuzzy is fixed to boolean rewrite. The other queries
have no longer any other modes. Only at some places in contrib are fixed
rewrite setting, whcih I simply remove.
Everywhere else, the defaults are already correct, RangeQuery & Co are gone
(deprecated) and the new ones were already in auto mode. The patch only
contains cleanup. We can close this soon.
I want to get out 3.0.
> Make constant-score rewrite the default for multi-term queries

> Key: LUCENE-1557
> URL: https://issues.apache.org/jira/browse/LUCENE-1557
> Project: Lucene - Java
> Issue Type: Improvement
> Affects Versions: 2.4.1
> Reporter: Michael McCandless
> Assignee: Uwe Schindler
> Priority: Minor
> Fix For: 3.0
>
>
> 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.
