>
> GlobalOrdinalsQuery holds a possibly large bitset of global ordinals that can
> pollute the query cache because the size of the query is not accounted in the
> memory usage of the cache.
> Moreover two instances of this query must share the same top reader context
> to be considered equal so they are not the ideal candidate for segment level
> caching.
