Hi Rainer,
The BBoxStrategy is pretty close to this. It does assume indexed
rectangles and not other shapes, and it’s limited to one rect value per
field, but perhaps this is fine for you nonetheless? See
the makeOverlapRatioValueSource() method. If this feature was non-obvious,

Hi,
If you would index additional grid ids for the bins, you could facet on them.
To me, Elasticsearch's Aggregation Module may also be a good fit.

Hi Parth,
Since Lucene 4.7 spatial, there is a “SerializedDVStrategy” for serialized
geometries. It’s used as a second-pass after RPT (or perhaps
BBoxStrategy). There was a presentation at FOSS4G about it (I was there
and helped with this one too):

There’s a small code
Hi Parth,
Lucene’s “terms dictionary” (an inverted index) is the physical
instantiation of the actual PrefixTree/Trie for numeric and spatial data.
It doesn’t know it is — it’s just a sorted list of keys pointing to
matching documents — it just so happens that the keys aren’t textual words
in this
Yes; as I said in my last sentence: "You’ll see a difference of Document vs
StoredDocument with 4x”.
As to SimpleCollector not being in 4x (I didn’t check but I’ll take your
word for it) — the bottom line is that you need to write a Collector, and a
simple one at that.

Thanks a lot for the reply David!
I am having some problems executing this code. I am using 4.8.1. I tried
looking for StoredDocument and SimpleCollector in the source code but
couldn't find them. Am I missing something?

Hi.
Your question is actually not particularly spatial; it’s more
circumstantial to your particular query. You want to know how to do a query
and collect *all* the results, in no particular order. To do this
efficiently, you need to use a Collector. Also, I noticed you are using
the “IsWithin” p

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 same
Hello Grant,

In LocalLucene, we use DistanceSortSource for sorting, which is no more.
How do we do distance sorting in Spatial?
Also, we use BoundaryBoxFilter to show all points visible in a zoomable

Hi Guillermo,
I think you will find that Lucene Spatial is going under a significant rewrite
in the coming weeks, so I'm hesitant to recommend you upgrading to it at this
point in time. That being said, the concepts behind Lucene Spatial and
LocalLucene aren't all that different, so it should
I had seen those, but they don't quite help on our problem of migrating from
LocalLucene 2.0 to Lucene Spatial. We don't use Solr.
Thanks though.
Anybody using Lucene Spatial, without Solr, wanting to share some code for
a basic geographical search?
