I meant, could we detect an input like `2160 Market St, San Francisco, CA` and avoid adding another ` San Francisco, CA` to the end? The implementation in mobile is naive (I think it just looks for commas) but helps a little. That also allows people to search outside of the survey location, in case multiple municipalities are involved or when we let folks browse through shared data.

I've seen people type in the entire address (number + street + city + state) on mobile, which is partly what motivated that code.
