Perform query based in existing map graphics

Question

Hi there,

I'm trying to create a function that performs a query on the map based in the current map.graphics. 
Is there an easy way to add map.graphics to the geometry parameter, besides going trough the map.graphics.graphics array to find the extents?

Thanks

The result may or may not be the same. For example a point which may be within the extend of a polygon may actually outside that polygon.

That's what I thought. As I see it for better performance use the extents, because you don't need the geometry service, and for accuracy use the join (right?).
By the way, is there a way to perform geometry operations (buffer, intersects, joins, etc) on the client side, without using the geometry services?

Ok, I understood that part, but I was wondering what's the best approach, and if the final result will be the same.

your approach used the extent of map.graphics.graphics as query.geometry while mine merged map.graphics.graphics into one geometry and used that geometry as query.geometry.
