When a locator is created, default parameters of the geocoding properties and options are saved in the locator. The geocoding properties and options control how the locator finds and filters the list of candidates, how it places the locations of matched addresses, the information that's contained in the geocoding output, and how geocoding performance is optimized. These geocoding properties can be set to meet specific use-case requirements.
Note:
To modify the locator's settings, it must be either added to the project or accessed from a folder connection 
in the Catalog pane under the Folders category 
.
