Is your feature request related to a problem? Please describe.
The search functionality does not work for our content. It hits the GitHub API limit after 2 searches. see https://answers.netlify.com/t/cms-search-hitting-github-api-limit/39124

Describe the solution you'd like

1. A configuration option to disable search entirely so our users don't hit the API limit
   This should be pretty easy to implement
2. Search that doesn't hit the API limit
   This could be a bit more difficult
