-------------------------------------
Hi David, I notice that the quad for polygon search is 3x faster than using
geohash.
The problem is that with its highest level (level = 29) it returns more results
than geohash with level 16.
So, it is 3x faster by less precise.
Would make sense to allow a higher level in the quads? Or this lack of
precision is due to other reason?

> Hi all, I have indexed the entire geonames points (lat/long) with JTS
> enabled, and I am trying return all points (geonameids) within a certain
> polygon (e.g. Netherlands country polygon). This query takes 3 minutes to
> return only 10.000 points. I am using only solr intersect. no facets. no
> extra fitering.
> Is there any configuration that could slow down such a query to less than 300
> ms?
