Looking at the filters, a lot of them have the same name, but because of case they map to different filterable objects. Screenshot attached below.
Assuming this data has already been written in the backend, but maybe a stored procedure or query could clean up existing data such as: "San Francisco" WHERE city_name IN ("San Francisco, "SF", "san francisco")
Or on the data ingestion side before this info is written a hashmap could be used to map San Francisco to all of its related phrases.
