[postgis-users] Topology GetRingEdges

I have established the schema and tables as outlined in the documentation example 11.8 TopoGeometry Constructors.
However, I am still missing something.
When I run GetRingEdges -
select topology.GetRingEdges('TEST', 1), entities.wkb_geometry
from entities, num_search
where st_intersects(entities.wkb_geometry, num_search.the_geom2);
The return are only the geometries which are actually intersected by st_intersects.(In this particular case only four of the eight lines that make up the polygon).
I was hoping the whole closed geometry to be returned.
What am I missing??
