[Geoserver-users] WFS problem with GeoServer and Solr.

Hello,

I’m having some trouble getting WFS to work with the Solr plugin for GeoServer. I have several polygons stored in Solr, and I’m able to load them onto a map using WMS just fine. However, when I try to use WFS, I get a syntax error from Solr. It seems like there is something wrong with the query that GeoServer is passing to Solr.

Here is the WFS request I’m using:

http://server:8080/geoserver/WORKSPACE/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=WORKSPACE:myLayerType&srs=EPSG:4326&format=text/javascript&format_options=callback:loadFeaturesBoundaries&bbox=-76.43702828511596,0,6.02966565566021e-11,76.43702828517625&callback=jQuery17201084845531731844_1424975764422&_=1424975764835

And here is the error I’m getting from Solr:

ERROR - 2015-02-26 14:30:09.373; org.apache.solr.common.SolrException; org.apache.solr.common.SolrException: org.apache.solr.search.SyntaxError: Cannot parse ‘layer_type:myLayerType AND :“Intersects(POLYGON ((-76.43702828511596 0, -76.43702828511596 76.43702828517625, 0.0000000000602967 76.43702828517625, 0.0000000000602967 0, -76.43702828511596 0)))”’: Encountered " “:” ": “” at line 1, column 35.

Was expecting one of:

“+” …

“-” …

“(” …

“*” …

“[” …

“{” …

“*” …

I noticed that there is a section in the Solr query, right after the ‘AND’ section where it is expecting an attribute name, but it’s just blank.

I manually modified the query generated by Solr, added the attribute, ran it against Solr directly, and it worked fine:

http://server:8983/solr/collection1/select?q=%3A&fq=layer_type%3AmyLayerType&fq=location%3A%22Intersects(POLYGON+((-76.43702828511596+0%2C±76.43702828511596+76.43702828517625%2C+0.0000000000602967+76.43702828517625%2C+0.0000000000602967+0%2C±76.43702828511596+0)))%22&wt=json&indent=true

I am using the following software versions:

GeoServer 2.7-RC1 (Running on Centos 7, tomcat 7.0.42, java version “1.7.0_75”)

GeoServer-2.7-SNAPSHOT-solr-plugin (From 2015-02-20)

Solr-4.10.3 (Running on CentOS 6, Jetty 8.1.10, java version “1.7.0_75”)

When I make the same request via WMS the ‘location’ attribute does show up as part is part of the query. Is there something preventing that part of the query being built when using WFS? Any help would be much appreciated!

Thanks,

Hi,
yes, this looks like a bug, the SOLR store is not handling properly the “default” geometry, which
is encoded as “” (the empty string).
Could you open a bug report here: http://jira.codehaus.org/browse/GEOS
(instructions on how to enter it, if you don’t have a login, are top left in that page)

Cheers
Andrea
