Subject [jira] [Updated] (SOLR-4586) Increase default maxBooleanClauses
Date Thu, 11 Apr 2013 20:03:16 GMT

     [ https://issues.apache.org/jira/browse/SOLR-4586?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yonik Seeley updated SOLR-4586:
-------------------------------

    Attachment: SOLR-4586.patch

Here's a simple patch that removes the max clauses limitation from Solr.

I considered going the deprecation route, but in this instance I believe most users would
be best served by outright removal of this trap since maxClauses was set by default in the
example solrconfig.xml.  Further, anyone who did actually explicitly set the value is most
likely just looking to avoid hitting exceptions.

> 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.
