Rob, That too is easy, if you have a spatial database as your backend (PostGIS, MsSqlSpatial, Oracle, DB2). We are doing something very similar on our HUD site. Many of the result sets have a ‘view in map’ link that uses the extents from the objects geometry to make a JavaScript call to re-center the map. If you follow that example, you should easily be able to duplicate the google maps search results.

You could search for 'estate agents' in 'London', and be presented with a list of estate agents on the left hand side of the screen, and the popups on the map. I want to present a list of features listed in tabular form, and clicking on the text navigates the map to the feature (popup).

My popup layer has over 17000 points, and when loaded as a Text layer, this means that there is a significant load on the browser. Is there an effective way of using the Google popups via some kind of spatial database, so that the requests can be spatially filtered at the server side (by database or geoserver or something) MTIA Rob No virus found in this incoming message.
