Geospatial search with multivalued field
Hi!
I'm trying to figure out how to enable spatial search for my use case.
I have documents that are in many cases associated with multiple geo
locations. I'd like to filter documents by the minimum distance to a
reference point (which is given at query time).
What this means is: If at least one of the locations of a document
lies within a certain radius of the point, it should be included in
the result.
Which field type can I use for this and how would I have to do the filtering?
Sorting (by distance) isn't relevant at this point, but it might be in
the future.
The example in Solr 3.4 states in schema.xml for the fieldType
"location" (field "store"): "A specialized field for geospatial
search. If indexed, this fieldType must not be multivalued." If I used
a field of type solr.LatLonType this would mean that I could have
multivalued="true", but no indexing? This means that I couldn't do
fast bounding box / range queries on the locations in order to narrow
down the result for a distance filter, correct? So wich one is better?
Thanks!
Marian

Hi Marian. I'm the author of Solr2155.
SpatialQueryable is an interface provided by Solr. Where did you put the
SOLR-2155 built jar file? Perhaps you put it where it doesn't belong like
in your servlet engine's lib directory (varies). You can put this in a
variety of places like embedding it into the Solr war, or in a shared lib
folder referenced by solr.xml or in a lib folder adjacent to your core's
conf directory, or finally any place referenced by a <lib> entry in
solrconfig.xml.
And you need a 3x release of Solr; trunk won't work for this.

Seems like I moved to the next failure. Now I get
java.lang.NoClassDefFoundError: org/apache/solr/schema/SpatialQueryable
during solr startup. Any idea where this sould be?
It seems to be required by the path
(src/main/java/solr2155/solr/schema/GeoHashField.java:public class
GeoHashField extends FieldType implements SpatialQueryable) but not
provided within the ZIP.

I tried "mvn package" without success. The error message wasn't clear
to me at first and I thought it was due to the wrong locations etc.
Then I found out that the .m2 directory in my home dir hat the wrong
write permissions, which caused the errors.
Now it worked. I gut the jar built. Will test geo filtering now or tomorrow.
Thanks again!

Marian,
My experience is not applicable to you directly, but David says
You'll need to run "mvn package" to generate a jar file that you can throw
into your classpath.
Have you got the jar ? You don't need to bother with Solr sources. Just
build jar and put it into Solr libs (see
http://wiki.apache.org/solr/SolrConfigXml#lib for reference). After that
amend you solrconfig/schema.xmls IIRC.

Mikhail, thank you! That explains a lot.
With the ZIP project, I still can't figure out where to put it and
what to apply it to. Do I have to put it into the 3.4.0-src folder
hierarchy? If yes, where exactly?

Marian,
Sorry, I completely forgot to mention.

The patch you tried to use is just my amendment for the David's zip. In
according to his comment it's already in Solr2155-1.0.3-project.zip.

OK, I would do that. But...
Against which version can/should I apply the patch? (I am not
restricted by other requirements so far.)
Then I tried both with the trunk and with 3.4.0-src, but I can't even
find the files the patch wants to modify. Some are moved, but others
don't exist.
Some of the files mentioned in the patch can be
solr/src/java/org/apache/solr/search/QParserPlugin.java
=> solr/core/src/java/org/apache/solr/search/QParserPlugin.java
solr/src/test/org/apache/solr/search/SpatialFilterTest.java
=> solr/core/src/test/org/apache/solr/search/SpatialFilterTest.java
lucene/contrib/spatial/src/java/org/apache/lucene/spatial/geometry/shape/MultiGeom.java
=> not found at all.
This was all for "SOLR-2155_GeoHashPrefixFilter_with_sorting_no_poly.patch".
For the file "Solr2155-for-1.0.2-3.x-port.patch", similar things
happen. E.g. "HaversineMultiConstFunction.java" isn't anywhere in the
3.4.0 src tarball.
What would I have to do in order to get any Solr version patched with 2155?
Thanks!

Some time ago I tested backported patch from
https://issues.apache.org/jira/browse/SOLR-2155
it works.
