Hi Zoran,

basically it just uses WFS Web Feature Service under the hood. So you need to understand that protocol.

If you have your geoserver running, try and do a GetFeature request with maxfeatures 10 on your layer/featuretype to ensure things are properly working on that side, so e.g.

http://foo/geoserver?service=WFS&request=GetFeature&typename=xxx&maxfeatures=10&version=1.1.0

After that configure your OpenLayers protocol which will be used by GeoExt search components.

Also, if you have not already done so, install Firebug to see the request response cycle.

Best regards,
Bart
