Minor Description
Currently, the maxBooleanClauses property is specified in most solrconfig's as the hardcoded value "1024". It'd be nice if we changed our shipped configs so that they instead specified it as <maxBooleanClauses>${solr.max.booleanClauses:1024}</maxBooleanClauses.
This would maintain the current OOTB behavior (maxBooleanClauses would still default to 1024) while adding the ability to update maxBooleanClauses values across the board much more easily. (I see users want to do this often when they first run up against this limit.)
