I am running solr 4.10.2 with geofilt (~20% of docs have 30+ lat/lon
points) and everything work hunky dori. Than I added a bf with geodist
along the lines of:
recip(geodist(),5,20,5) .... after few hours of running I end up with OOM
GC overhead limit exceeded. I've seen this
https://issues.apache.org/jira/browse/LUCENE-4698 and few other relevant
tickets. Wanted to check if anyone has any successful remedies.

Many thanks,
Mihran
