Yonik Seeley commented on SOLR-4586:
------------------------------------
bq. I disagree with Integer.MAX_VALUE (as i said on LUCENE-4835)
The argument there seemed to be more about Lucene (a programmer bug that kept
adding clauses), although this is an extremely weird way to help catch such an
error.
Put another way... if the static max clauses had never existed, would it be
added today? I don't think so. It was added in the past for historical
reasons (auto-expanding queries) that hopefully no longer apply today.
Anyway, for Solr-land, if we want to enforce on a per-core basis then we can do
that at the Solr query parser level. I see no reason to do that though. I
think we should just remove the limit altogether at the solr level.

> 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.
