 ### Changes
 
 - OpenSearch backend now uses multiple indices to store document metadata, this avoids unnecessary duplication of said metadata and allows us to more easily reference specific documents in the collection.

 - Some of the CLI scripts have been renamed to be more consistent and better fit the new database schema.
-- Use volumes managed by Docker instead of mounting directories from the host OS. This allows us to resolve some issues with permissions that may have been preventing Linux users from using the app.
