Hello, all
When i use the geoserver sample data to test a getfeature request. I want to use a filter to get the specified tiger_roads feature, but the response returned all the roards without filtering. I could not find the solution. The request is in the following:
Any comment? thanks a lot!
<wfs:GetFeature service=“WFS” version=“1.0.0”
outputFormat=“GML2”
xmlns:tiger=“http://www.census.gov”
xmlns:wfs=“http://www.opengis.net/wfs”
xmlns:ogc=“http://www.opengis.net/ogc”
xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=“http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd”>
tiger:NAME
Washington Sq W
</wfs:GetFeature>

When GeoServer makes a WMS request, it can only filter with the bounding box, and scale as specified in the SLD document. This is because of tricky if/else filter clauses in SLD documents that cannot be passed on easily to the datastore. So it requests all of the data (that fits in the bounding box) and then runs the filter on each feature. There is a plan to improve this, don't worry. =)

You need a 'Filter' in your query, around the PropertyIsEqualTo. See the example requests in the demo section of GeoServer. And check the Filter specification. Your request must follow the rules of the XML for Filters.
<Query typeName="tiger:tiger_roads">
<Filter>
<PropertyIsEqualTo>
<PropertyName>tiger:NAME</PropertyName>
<Literal>Washington Sq W</Literal>
</PropertyIsEqualTo>
</Filter>
</Query>
I think is what you need.
