Re: SOLR4 Spatial sorting and query string
This is a known limitation. From CHANGES.txt: * SOLR-2345: Enhanced geodist() to work with an RPT field, provided that the field is referenced via 'sfield' and the query point is constant. (David Smiley) The reason why that limitation is there relates to the fact that the function query parser will attempt to resolve the field name if it's referenced as an argument, and that'll fail because you can't get a ValueSource from an RPT field because a ValueSource is a single-valued construct and RPT isn't limited in that way ~ David Billnbell wrote David, We noticed in 4.5 that sort=geodist(store_geohash) asc does not work anymore.

Re: SOLR4 Spatial sorting and query string
Great, it works very well. In solr 4.5 i will use geodist() again! Thanks David -- View this message in context: http://lucene.472066.n3.nabble.com/SOLR4-Spatial-sorting-and-query-string-tp4084318p4084487.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: SOLR4 Spatial sorting and query string
Hello,
I have a question about performance with a lot of points and spatial search.
First i will explain my situation:
We have some products data and want to store every geo location of stores
that sells this product.
I use a multivalued coordinates field with the geo data:
arr name=store_coordinates
strlat,long/str
strlat,long/str
strlat,long/str
strlat,long/str
strlat,long/str
/arr
The config:
*field name=store_coordinates type=location_rpt indexed=true
stored=true multiValued=true/
fieldType name=location_rpt
class=solr.SpatialRecursivePrefixTreeFieldType distErrPct=0.025
maxDistErr=0.09 units=degrees/*
When i search for a product term i want only the products that are nearby
the given location. So i used to following query:
fq=_query_:{!geofilt sfield=store_coordinates pt=locatonlat,locationlong
d=25}
It works great but my question is: Will it work quick and smooth with +1000
stores in my store_coordinates field?
Any help is appreciated
Thanks,
Roy

Re: SOLR4 Spatial sorting and query string
Roy,
How fast/slow this is is dependent on the total number of points in
documents that match the search results. If one of those documents has
1000 points but most have a handful then it isn't such a big deal. The
bigger problem is: https://issues.apache.org/jira/browse/LUCENE-4698

SOLR4 Spatial sorting and query string
Hello,
I use the following distance sorting of SOLR
4(solr.SpatialRecursivePrefixTreeFieldType):
fl=*,scoresort=score ascq={!geofilt score=distance filter=false
sfield=coords pt=54.729696,-98.525391 d=10}
(from the tutorial on
http://wiki.apache.org/solr/SolrAdaptersForLuceneSpatial4)
Now i want to query on a searchstring and still want to sort on distance.
How can i combine this in above solr request? When i add something to the
q= it doesn't work. I tried _query_ subquery and other stuff but i don't
get it working
I appreciate any help,
Thanks

Re: SOLR4 Spatial sorting and query string
Hi Roy.
Using the example schema and data, and copying the store field to
store_rpt indexed with location_rpt field type, try this query:
http://localhost:8983/solr/select?indent=truefl=name,storeq=*:*sort=query%28{!geofilt%20score=distance%20filter=false%20sfield=store_rpt%20pt=45.15,-93.85%20d=0%20v=%27%27}%29%20asc
sort spec without url encoding: query({!geofilt score=distance filter=false
sfield=store_rpt d=0 v=''}) asc
One of the tricks there is that it's sorting on the query() function query,
which references a query that has its score used as the result of query().
And you put a spatial query in there (note: score=distance only works with
rpt), and voila. The fact that v='' is needed appears to be a Solr bug. I
realize this is super awkward, so this approach isn't well documented if at
all. In Solr 4.5 you can simply use geodist().
Note: if you have only one point per document, I recommend sorting by
LatLonType.
