I am getting an odd result set returned from TS searching. Here is my index
definition:
<pre><code>
# Thinking Sphinx #############################################
define_index do
indexes :name
indexes :description
indexes tags.name, :as => :tag_name
indexes city.name, :as => :city_name
has "RADIANS(locations.latitude)", :as => :latitude, :type => :float
has "RADIANS(locations.longitude)", :as => :longitude, :type => :float
set_property :latitude_attr => :latitude, :longitude_attr => :longitude
end
###############################################################
</code></pre>
I run searches based on distance from a lat/lon pair that is determined by
current location or center of city lat/lon. The basic search is as follows:
<pre><code>
c = City.find_by_name("New York City")
Location.search(:geo => [c.latitude, c.longitude], :order => "@geodist ASC")
</code></pre>
This should find the 20 closest locations to the center of New York City,
but instead it finds 20 locations in Austin, Texas. If I instead search for
the closest locations to the center of Austin, TX I get locations in San
Diego, CA. San Diego returns Seattle, WA. Seattle returns Miami, FL. I have
verified the lat/lon pair of each of these cities and the location lat/lon
is automatically generated by a call to google maps.
In addition, the results are in order of distance from the supplied
lat/lon, they just aren't the closest by far.
Is there some other config I'm missing? Did I do something wrong? Any help
is much appreciated.
