Hi all,

I’m trying to use geo-location based search using ultrasphinx, Here my  
search query.

@search = Ultrasphinx::Search.new(:sort\_mode =\> ‘extended’, :sort\_by  
=\> ‘distance’, :location =\> {:units =\> ‘degrees’, :lat =\>  
40.7414, :long =\> -74.0014})  
@search.results.collect{|x| x.distance}

It return result properly

[0.69084495306015, 400.852783203125, 8684957.0]

But when using :query it returns distance as NaN

@search = Ultrasphinx::Search.new(:query=\>“sr.software”,:sort\_mode =\>  
‘extended’, :sort\_by =\> ‘distance’, :location =\> {:units =\>  
‘degrees’, :lat =\> 40.7414, :long =\> -74.0014})  
@search.results.collect{|x| x.distance}

[NaN, NaN, NaN]

Please suggest one good solution to use both :query and :location
