To determine “the smallest polygon which contains the point” for t
I was wondering about the feasibility / difficultly of implementing a
solution to the following problem with Lucene.
For each document, I have a series of nested polygons each associated
with a numerical value. My search query gives a point, and I want to
return all of the documents whose largest
The new Spatial contrib module has already implemented what I was talking.

n I combine the geoquery with another query through
booleanquery. I do really appreciate if you could give me a little help to
get the distance value and sort the items based on their distance

be better served working with Lucene directly instead of Solr (or Solr's
Lucene based competitors).

The old tier-based stuff in Lucene is broken and considered deprecated.
For Lucene, this may currently be your best hope:

Hello,
I am trying to add spatial search functionality to my application, but
having a trouble regarding lucene's spatial search.
It's very simple functionality: searching all items within given radius from
given starting point.

Below is TestCartesian class. In this class, I changed starting position and
predefined positions in addData method to be around 37.504602,127.049031.
The problem is that as I increase the search radius, after some threshold,
spatial search returns nothing when it should return at least the

Hi all!
I need 1) sort search results by distance from some point and 2) show
these distances for end-user together with other document information.
1) is simple – like an example in “Lucene in action”: there are
latitude and longitude fields for each document in index,

Hi, what is the most efficient way of doing a spatial search in this way.
I have persons who monitor an area. I am at position x and I want to find
whether I fall within those monitored areas. If I do then they can monitor
me.
What is the best method for doing this type of search. The simplest
Hi everyone,
I've been using lucene spatial for the last few months without

I'm posting 2 unit tests to demonstrate the issue - the first based on

Could be I'm missing something obvious and would appreciate a
