Nicholas Knize updated LUCENE-6685:
-----------------------------------
    Attachment: LUCENE-6685.patch

Updated patch iincludes the following improvements:

* Dynamically compute detail level based on query size (includes min/max bounds 
on detail level)
* Remove unnecessary ranges from PointDistanceQuery

> GeoPointInBBox/Distance queries should have safeguards

> These queries build a big list of term ranges, where the size of the list is 
> in proportion to how many cells of the space filling curve are "crossed" by 
> the perimeter of the query (I think?).
> This can easily be 100s of MBs for a big enough query ... not to mention slow 
> to enumerate (we still do this again for each segment).
> I think the queries should have safeguards, much like we have 
> maxDeterminizedStates for Automaton based queries, to prevent accidental 
> OOMEs.
> But I think longer term we should either change the ranges to be enumerated 
> on-demand and never stored in entirety (like NumericRangeTermsEnum), or 
> change the query so it has a fixed budget of how many cells it's allowed to 
> visit and then within a crossing cell it uses doc values to post-filter.
