[jira] Created: (LUCENE-1557) Make constant-score rewrite the
default for multi-term queries
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: Michael McCandless
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.

---------------------------------------
Sorry, the SpanRegExQuery must stay unmodified, because it relays on BooleanQuery.

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.

-------------------------------------
Uwe, I am a little confused about this issue. The MultiTermQuery now has a lot of smarts with regards to this. I feel it is obselete
Is this kept open just for the FuzzyQuery?

This issue is no longer relevant. All classes were deprecated in 2.9 and now removed and there is nothing to change anymore.
