The Lucene geo searching code is very fast. Geosearch queries
calculate the distance from the city to all 20k stores and sort on
this.
If this is not fast enough, you can pre-calculate the city/store lists
by doing all of this searching in advance. You can store these in a DB
and do incremental up
Sorry for not being clear enough.
I don't know the point of origin. All I know is that there are 20K retail
stores. Only the cities within 10 miles radius of these stores should be
searchable. Any city which is outside these small 10miles circles around these
20K stores should be ignored.
So w
But again, that doesn't answer the problem I posed. Where is your
point of origin?
There's nothing in what you've written that indicates how you would know
that 10 miles is relative to San Francisco. All you've said is that
you're searching
on "San". Which would presumably return San Francisco, San
So let's say x=10 miles. Now if I search for San then San Francisco, San Mateo
should be returned because there is a retail store in San Francisco. But San
Jose should not be returned because it is more than 10 miles away from San
Francisco. Had there been a retail store in San Jose then it shou
I don't see how this works, since your search for San could also return
San Marino, Italy. Would you then return all retail stores in
X miles of that city? What about San Salvador de Jujuy, Argentina?
And even in your example, San would match San Mateo. But should
the search then return any stores
I don't think Spatial search will fully fit into this. I have 2 approaches in
mind but I am not satisfied with either one of them.
a) Have 2 separate indexes. First one to store the information about all the
cities and second one to store the retail stores information. Whenever user
searches fo
I believe that what you need is spatial search...

Hello,
I have a design question for Solr.
I work for an enterprise which has a lot of retail stores (approx. 20K).
These retail stores are spread across the world. My search requirement is
to find all the cities which are within x miles of a retail store.
So lets say if we have a retail Store i
