Subject [jira] [Commented] (SOLR-4586) Increase default maxBooleanClauses
Date Mon, 03 Nov 2014 22:36:34 GMT

    [ https://issues.apache.org/jira/browse/SOLR-4586?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14195253#comment-14195253

Shawn Heisey commented on SOLR-4586:
------------------------------------

That's correct.

It is entirely possible that this is one config setting that does not get re-handled on a
core reload.  I'd have to trace the code to know for sure, and I'm not very familiar with
it, so it could take quite a while to trace.  I don't have the time for that at the moment.

> In the #solr IRC channel, I mentioned the maxBooleanClauses limitation to someone asking
a question about queries.  Mark Miller told me that maxBooleanClauses no longer applies, that
the limitation was removed from Lucene sometime in the 3.x series.  The config still shows
up in the example even in the just-released 4.2.
> Checking through the source code, I found that the config option is parsed and the value
stored in objects, but does not actually seem to be used by anything.  I removed every trace
of it that I could find, and all tests still pass.
