Yes. Generally it's assumed you can find a hurled weapon without problem after combat, as they're much larger and sturdier than general ammunition. If your GM has a rule how he wants it done, you might want to ask them though.
The rules are, move into the square you threw it in, move action to pick it up, move action to put it away.
They don't get broken like ammunition on hits, and don't have a 50/50 chance to be lost like missed ammunition. Assume it lands in the square you threw it at, and pick it up when you get there. Or if you miss, assume it goes to the end of the range increment in a straight line. There's no RAW for it, so go with whatever sounds good.
RAW: They aren't destroyed, but it doesn't say where they go.
I think the only exception are shuriken, I recall them being treated like ammunition since you can throw more than one at a time, but that may just be old 3.0 rules I'm recalling.
Rules-as-written doesn't cover thrown weapon recovery.
If you want the detail, I'd suggest lost or broken on a natural 1. If you want to track location of misses during combat use the splash weapon rules for scatter.
