String data from a binding. Can someone confirm this? What would it take
to expand that?
I can see that Javascript.g4 (Antlr grammar) references a "STRING" but
can't make out if/how it's used in JavaScriptCompiler.

Yup. And if you have the original lat/lon then you can forgo the

Yes. There's a lot already there but you'd need to subclass some stuff to
add some other predicates. See CompositeSpatialStrategy and

Hi Tom,
If you qualify the solution as using BKD (what Lucene now calls
"PointValues") then -- no. But that's an implementation detail. In terms
of capabilities, if you want to index polygons (as represented on the
surface of a sphere, not 2d) in Lucene, then it's possible. See
Geo3dRptTest. I
I like how you figured out how to add DocValues without having to modify
PointVectorStrategy at all -- nice.
But I think you are completely using PointVectorStrategy, even for
filtering (query)? It does a relatively slow job at that; I suggested
using RecursivePrefixTreeStrategy for the filtering
Oh yes So in 5.x there was no DocValues option for this
SpatialStrategy impl which is a shame of course. You could take the code
for 6.x:
https://github.com/apache/lucene-solr/blob/branch_6x/lucene/spatial-extras/src/java/org/apache/lucene/spatial/vector/PointVectorStrategy.java
and back p
As I mentioned that PointVectorStrategy has an argument that accepts a
Lucene FieldType that you can add docValues to.

Hi "sc",
I suspect you are hitting OOM for makeDistanceValueSource call on
RecursivePrefixTreeStrategy. That strategy is best for filtering (the
query), but it's a memory pig for distance sorting requirements. Instead,
use PointVectorStrategy for the makeDistanceValueSource purpose. For that

If there are no filters, then LatLonDocValuesField is going to be asked to
sort all of your docs, which is obviously going to take awhile. Can you
simply add a filter? Like a distance filter using LatLonPoint?

I know I'm late to this thread, but I saw this and specifically "reverse
geocoding" and it caught my attention. I recently did this on a public
project with Solr, which you may find of interest:

Looks like you should use the original Highlighter until requirement #2,3
can be done with the UnifiedHighlighter. Other than #2,3, the UH can
handle all these requirements, and the OH can do all.

I was recently asked if/how the UnifiedHighlighter can return a Passage
centered around the highlighted words. I'm responding to a wider audience
(java-user list, ...).
Each highlighter implementation fragments the content into passages (with
highlights) using a different algorithm.

Hello Randy.
If you are on Lucene 6x, or possibly some late 5x releases, there are newer
Lucene spatial implementations that have fewer moving parts to them and so
will be simpler. I'm almost certain they would be fastest too, although
perhaps that's not much of an issue with only 100k's of data
It would help tremendously if you can give a specific code example showing
the problem.

Hi James,
The spatial module in v4 is completely different than the one in v3. It
would be good for you to review the new API rather then looking for a 1-1
equivalent to a class that existed in v3. Take a look at the top level
javadocs for the spatial module, and in particular look at

DiskDocValues is a codec (or part of a codec, apparenlty) for accessing the
DocValues from disk, with minimal RAM usage for things like offsets.
Lucene42Codec alternatively puts all of DocValues in RAM. Is the actual
disk resident data format the same between them? And how do you pick &

Amir,
CachedDistanceValueSource is indeed poorly named; I need to get renaming it

computationally cheap enough to calculate for the X number of results

Amir,
The geo query's score happens to be the distance but I don't expect that
to remain so. I plan for it to be 1/distance which is a better relevancy
value -- a "score" is supposed to be about relevancy after all. If you want
to get the distance for a search result, I recommend calculating it
