title: Get GeoJSON from GeoServer with filter
body: <p>I have published a map service in GeoServer, and there are thousands of features in there.
  When I generate GeoJSON from Layer Preview with out "maxFeatures=50", the process is getting extremely slow. So I was wondering that if there is a way that I can put some filter in the request url so I can get specifically what I want instead of all features?</p>
  
  <p>For example, I want get features whose name equals to "test", can I make the url:</p>
  
  <p><a href="http://domain.com:8188/geoserver/ows?service=WFS&amp;version=1.0.0&amp;request=GetFeature&amp;typeName=Gistic:V_STRUCTURES_WFS&amp;outputFormat=json&amp;name=test" rel="nofollow">http://domain.com:8188/geoserver/ows?service=WFS&amp;version=1.0.0&amp;request=GetFeature&amp;typeName=Gistic:V_STRUCTURES_WFS&amp;outputFormat=json&amp;name=test</a></p>
  
  <p>in order to filter?</p>
  
  <p>If not, is there any other way to do it?</p>
  
  <p>Thanks </p>
