Hard to explain.. :) The search terms are user-entered - look at my
screen shot: http://zoran.name/ty_form.png
Assume
- hamburg has 100 hotels
- berlin has 1 hotel
- distance between cities: 289 km
- range for geodist: 280 km
A user search for "Berlin" by clicking on the "Hotel" button. He will
get only the 1 hotel in Berlin and probably hotels in Hamburg which
have "Berlin" in their names. That's right but I want to show him
other hotels in range as well because he clicked on "Hotel".
I should mention that I first check the user input for city names. If
the search string contains a city name, it will be used for geodist.
Something like this:
geo_city = City.search params[:user_input]
if geo_city.size == 1 && !geo_city[0].id.to_s.blank? && !
geo_city[0].lat.to_s.blank? && !geo_city[0].lng.to_s.blank?
city_lat = (geo_city[0].lat / 360.0) * Math::PI * 2
city_long = (geo_city[0].lng / 360.0) * Math::PI * 2
city_radius = geo_city[0].radius.to_f * 1000.0
@results = Tip.search params[:user_input], :conditions =>
{:theme_name => params[:theme]},
:geo => [city_lat, city_long],
:with => {'@geodist' => Range.new(0.0, radius)},
:order => "@weight, @geodist ASC",
:per_page => 50
end
Cheers
Zoran
