RangeQuery & TooManyClausesException : Lucene 2.4
Hi,
Looking at the docs for the 2.4 codebase, for RangeQuery
http://lucene.apache.org/java/2_4_0/api/index.html?org/apache/lucene/search/RangeQuery.html
there is a comment that a TooManyClauses exception is no longer thrown.
Does this mean that it is now safe to use RangeQuery without worrying
about excessive term expansion? Has the implementation changed such that
it is no longer constructing multiple BooleanQuery terms to perform a
range query?
Thx,
Joel

Woops -- disregard my comments. I was looking at the unreleased
(2.9-dev) version of RangeQuery.
In 2.4, RangeQuery will throw TooManyClauses, if the number of terms
in the range exceeds BooleanQuery's maxClauseCount.
ConstantScoreRangeQuery will not throw that exception.

Hi,
I did not see method setConstantScoreRewrite method
in RangeQuery class?

Hmm... that's actually not true: RangeQuery will still throw that
exception, unless you call setConstantScoreRewrite to true (at which
point it does the same thing as ConstantScoreRangeQuery, ie that
exception will not be thrown).
The javadoc for RangeQuery is very misleading. (This happened when we
absorbed ConstantScoreRangeQuery into RangeQuery, for 2.4).
I'll fix RangeQuery's javadoc.

Hmm... that's actually not true: RangeQuery will still throw that
exception, unless you call setConstantScoreRewrite to true (at which
point it does the same thing as ConstantScoreRangeQuery, ie that
exception will not be thrown).
The javadoc for RangeQuery is very misleading. (This happened when we

I'll fix RangeQuery's javadoc.
