Jan Høydahl commented on SOLR-4586:
-----------------------------------

Pri 1 is to resolve the "last-core-wins" bug, whether it happens through 
LUCENE-7880 or some other means. Not entirely sure what this statement means 
though:
bq. if we set the static to MAX_INT and do the max_clause checking ourselves
Where exactly would we add that new max_clause check? In the query parsers?

> Eliminate the maxBooleanClauses limit

> 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.
