-------------------------------------
Summary: Remove enforcing of Filter Rewrite for NRQ queries
Key: LUCENE-4235
URL: https://issues.apache.org/jira/browse/LUCENE-4235
Project: Lucene - Java
Issue Type: Improvement
Components: core/search
Reporter: Uwe Schindler
Assignee: Uwe Schindler
Fix For: 4.0, 5.0
Back in Lucene 2.9, I hardcoded NRQ to always use filter rewrite based on the
precisionStep. This is bogus and contradicts our autodetection (which may need
some overhaul now in Lucene 4.0).
If a query rewrites to only one term, using filter rewrite is stupid and slows
down a lot, it can do a simple CSQ(TermQuery()) which is incredibly fast.
This issue will remove the line from the CTOR.
