Erick Erickson commented on SOLR-4586:
--------------------------------------
Jan:
Got it. I think moving it to solr.xml is sub-optimal, but much better than what
we do now. Putting it in solr.xml conveys that it's an instance-wide setting
_much_ better than putting it in solrconfig.xml.
And functionally this is no different than what we do currently in the sense
that to be useful _all_ the solrconfig files for _all_ the cores in the JVM
need to have the same setting. Which means you can't have one core respect one
limit and another core respect another limit.
Which would be just what putting it in solr.xml would do too. The solr.xml
option makes it a lot less trappy.

> 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.
