color:#1F497D'>Currently, I do a filtered WFS request then I scan the geometry
of all the polygons returned to the application and calculate a BBox for each;
then I add to bounds and I end up with a BBox that includes my whole collection
of filtered polygons. This process can be slow given the number of polygons and
their size. To mitigate this I have preprocessed the polygons and added a BBox
attribute on each polygon record inside the DB which means I can avoid the
geometry parsing but I do not think I can avoid the WFS download which is now
my bottleneck.<o:p></o:p></span></p>

<p class=MsoNormal>Hello, I am working on an OpenLayers / GeoServer project and
am trying to utilize the Filter tool, which is built into the GeoServer 1.7.0
OpenLayers preview template. I would like to be able to zoom to the extent of
the filtered features- so the user can basically enter a search, which performs
a filter and zooms to the results. Is there any way to grab the extent of the
current filter and perform some kind of ZoomtoFilterExtent call? My question is
very similar to this post: http://www.nabble.com/searching-a-feature-with-open-layers-td13724745.html#a13761443
Thanks! <o:p></o:p></p>
