Hi Jackson,
Google Groups isn't the place to post specific technical issues or questions, as this forum is meant more for general discussion of the platform and services.
If you've searched everywhere you can for a feature and can't identify that it exists, you should proceed to open a public issue tracker [1] feature request with enough detail to determine exactly what you'd like implemented (here the ability specify an alternate location for local_search.bin).
If you would like to open a thread in this forum discussing the platform or services in more broad terms, starting a discussion that would be useful for other users to join in to, feel free to do so.
Have a great day!
