Possible option to process search when user is done typing instead of autocomplete?

[Wmeng98]

With the current policy set for Google places API usage and billing, it seems the free 150,000 requests per 24 hours is no longer provided and replaced with a $200 monthly credit.

Autocompletion of users queries as they type becomes more costly now.
Would it be feasible to introduce an option to process the query once the user has finished typing?

Two options came to mind...

1. Only process the query when the user presses the search button
2. Introduce a timer delay to process queries X time after user has finished typing (not sure if this is already in the implementation)
