Hi all,
I've been using solr 1.4 and it's working great for what I'm
doing. However, I'm now finding a need to filter results by location.
Searching around, I see that the distance functions are implemented in
solr 4.0, but there's no full release yet.
So my question is, is solr 4.0-dev ready to be used in prime time? My
other option would appear to be using the cartesian distance, which
isn't totally accurate, but it probably good enough for my purposes.
Something like including this in my filter query:
sum(pow(sub(input_latitiude,stored_latitude),2),pow(sub(input_longitude,stored_longitude),2))<degrees
distance filter
What's anyone else out there using?
Thanks in advance,
Alex
