: Thanks for your reply. Nested boolean queries is a valid concern. I also : realized that isCoordDisabled needs to be considered in : BooleanQuery.hashCode so that a query with coord=false will have a different : cache key in Solr.
Hmmm... you're right, BooleanQuery.hashCode doesn't consider disableCoord.
that's a nasty bug...
