[mapserver-users] WFS featureislike and bbox filter required?

[mattmendick]

Hi All-

I'm trying to query mapserver's wfs service (layer's data is backed by
postgis) using the following post: (excuse the parentheses instead of <>'s,
they are from some debug code)

(wfs:GetFeature service="WFS" version="1.1.0" resultType='results'
xmlns:wfs="http://www.opengis.net/wfs"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:gml="http://www.opengis.net/gml") (wfs:Query srsName="EPSG:4326"
typeName="ms:delaware_highway")
   (ogc:PropertyName)name(/ogc:PropertyName) 
   (ogc:PropertyName)geom(/ogc:PropertyName)
   (ogc:Filter) 
      (ogc:PropertyIsLike wildCard="*" singleChar="." escape="!")
         (ogc:PropertyName)name(/ogc:PropertyName)
         (ogc:Literal)*Wil*(/ogc:Literal)
      (/ogc:PropertyIsLike)
(/ogc:Filter)
(/wfs:Query)
(/wfs:GetFeature)


I don't get back any results, but when I specify a bounding box, let's say a
global bounding box to make it easy, I get back all the relevant results.

(wfs:GetFeature service="WFS" version="1.1.0" resultType='results'
xmlns:wfs="http://www.opengis.net/wfs"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:gml="http://www.opengis.net/gml") (wfs:Query srsName="EPSG:4326"
typeName="ms:delaware_highway")
   (ogc:PropertyName)name(/ogc:PropertyName) 
   (ogc:PropertyName)geom(/ogc:PropertyName)
   (ogc:Filter)
      <ogc:And>
         <ogc:BBOX>
            <ogc:PropertyName>geom</ogc:PropertyName>
            <gml:Envelope srsName="EPSG:4326">
                <gml:lowerCorner>-180 -90</gml:lowerCorner>
                <gml:upperCorner>180 90</gml:upperCorner>
            </gml:Envelope>
         </ogc:BBOX> 
         (ogc:PropertyIsLike wildCard="*" singleChar="." escape="!")
            (ogc:PropertyName)name(/ogc:PropertyName)
            (ogc:Literal)*Wil*(/ogc:Literal)
         (/ogc:PropertyIsLike)
      </ogc:And>
(/ogc:Filter)
(/wfs:Query)
(/wfs:GetFeature)

Is the bbox filter necessary to do a property is like?  When I don't specify
the bounding box, the postgres query has this intersect clause: where
wkb_geometry && GeomFromText('POLYGON((-1 -1,-1 -1,-1 -1,-1 -1,-1 -1))

Is this trying to tell me that I need to add the bbox, or is this a bug?

Thanks for your help!
