Bob- I don't know what would be involved in using this method with
aaf, but I am using this method for a bounding box geo query. If you
need a more strict radial search you can use a custom filter with
0.10.x.
During index population I'm doing:
doc << Field.new("latitude", latitude.to_f + 1000,
Field::Store::NO, Field::Index::UNTOKENIZED)
doc << Field.new("longitude", longitude.to_f + 1000,
Field::Store::NO, Field::Index::UNTOKENIZED)
and during the query I'm doing:
query << "latitude:[#{box[:lat_min] + 1000} #{box[:lat_max] + 1000}]
AND "
query << "longitude:[#{box[:lon_min] + 1000} #{box[:lon_max] + 1000}]
AND "
I have helper methods outside of this scope to handle the min/max
that I'm searching in. I also have a complete (yet untested)
GeoFilter, but we aren't using the .10.x Ferret yet so I have no idea
if it actually works.
