I'm sure that is better than not being able to find any in a  
particular area.

How often will the index be updated? As often as the planet.osm file?  
I'm wondering when things are going to start re-rendering since the  
rails port update, so that I can see my changes.

One thing that has shown up when trying out some of the searching  
with this tool is the use of the is_in tag. Basically the is_in tag  
isn't used anywhere near like enough.
