But clicking on a country in a map showing the countries shape file, there is no element in the resulting feature collection (variable featureCollection down below). Omitting the bounding box filter gets a list of all countries (as expected).

You may want to try using a different spatial relationship (other than 
BBOX) to select the contents, I have often found that making a polygon 
and using a NOT( DISJOINT) test works well. You can also try INTERSECTS 
etc..

I am a bit confused as I understand that shapefile supports the BBOX 
operation especially; actually makes use of the spatial index etc for 
speed.  I expected the example to work as written.

Cheers,
Jody
