geocode then query?

Question asked by empicard on Mar 30, 2012
Latest reply on Apr 2, 2012 by empicard
I'd like to run a geocode on a single address, and then query a polygon feature (and eventually buffer depending on the results of the query - im sure i'll have more questions about that shortly!).
I Started with the geocoding sample, but I'm having a lot of trouble figuring out the
query.geometry part of it.
