### Function
Accepts a list of terms. Terms are searched against the ```name_``` column in ```admin1_synonyms_qs```. The ```name_``` column is an automatically cleaned and populated column based on the raw values in ```name``` . The synonym table returns the proper global_id (based on rank values in table below). The global_id is then matched against the single row in the ```adm1``` table to return the correct polygon(s).

This is an improvement made based on tickets/issues submitted by users when geocoding admin1 states / provinces.
