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.
