Geo field proximity distance for exact location I'm tried this for a day,but i won't get the answers. I'm using geo field proximity for zip code searching, it's working with 5,25,30 miles search, but i want to search exact location of zip code.

eg
    In search zip code : 73301, all the record in 73301 will be show.
Zip codes don't have exact location. A zip code is an area in which the coordinates are a point within it. In most cases it is probably the centroid.
