Result Biasing - how to include results only in a single US state?

Hello,

I have geocoded a Location field from a street address field, and I have set up a Gmap view to display all of the entity locations. All of my entities/locations are in the US state of Florida. I am running into an issue where "123 Main St" might be in Florida, or California, or any other state, and therefore my map is showing some of the non-Florida versions of those locations.

I began investigating the Result Biasing settings in the Location field, but I am not sure how to format the string to filter the results. I assume Component Filtering would be the way to go... what string would I use to filter by the state (AKA administrative_area_level_1)?

Thanks!
