Hi Gus,
Thank you for your reply. I am trying to emulate an existing API that is why I
am trying to work with the Zipcode directly. After looking at this it looks
like I will have to do a few things.
1. When indexing I will need to index the location in a spatial field
<fieldType name="location" class="solr.LatLonPointSpatialField"
docValues="true"/>
2. Along with the zipcode (in case just a straight zipcode match is desired)
I will have to lookup the GPS coordinates of the zipcode and pass them as the
pt parameter.
3. Finally, I will need to use the functional query geodist() to return a
field that will be the distance from the location in item 1 and the pt
parameters in item 2.
Does this sound about right?
Thanks

Hi Matthew, It's worth keeping in mind that if you are *starting* with user
input that has a zip code ("where zipcode is provided as a parameter?"), then
it's faster at query time if you index the documents with a zip code and just
match zip

Hi Matthew,
It's worth keeping in mind that if you are *starting* with user input that
has a zip code ("where zipcode is provided as a parameter?"), then it's
faster at query time if you index the documents with a zip code and just
match zip codes. If your documents have GPS points but not zipcodes or
only some have the zip code, calculate the zip code (when required) during
indexing and add it to the document. Do the work during indexing whenever
possible. Geo queries would tend to come into play if you were starting
with a GPS point and wanted documents within a radius, or within a polygon
defined by the user, etc.
One could do radius from a centroid of a zip or something like that, but
that's pretty coarse, and unless the distances are tens of miles or more,
distances from an address (located to a GPS point via a service) would
often be more valuable to the user since zip codes can be quite large in
rural areas, and sometimes have funny shapes.
Best,
Gus
