Subject Re: Term Dictionary taking up lots of memory, looking for solutions, lucene 5.3.1

   I have similar requirement of searching points within a radius of 50m.
Loaded 100M latlon, indexed/searching with LatLonDocValuesField. I am
testing it on my macbook pro. 

I have used all Directory(RAM/FS/MMap) types but it takes 3-4 secs to do
search/sort to return of 5 points with in radius of 50m.

I am looking to reduce search/sort time to 10ms. I have 4g of RAM for the
java process which is more than sufficient.

Any suggestions greatly appreciated.
