        Hello,
you are right, the idea about Notmuch is to provide an email indexer for
the local-based mail providers [1], thus the actual folder searching
will be able to use the Notmuch "database" and speedup the actual
search.

That's basically the student's task.

I do not think it's necessary to go too much into the detail right now,
maybe just start with the maildir provider, which is used for On This
Computer messages. As you can see
at [1], it consists of three objects:
- CamelMaildirStore - it gives an information about folders in
  the store and manipulates with them on the folder structure level;
- CamelMaildirFolder - it represents a folder content, including messages;
- CamelMaildirSummary - it represents a summary of the folder, which
  basically provides enough information to be able to populate
  message list in evolution without opening any message. It is also
  used when the folder is searched.

By traversing the object hierarchy you may see what the parent objects
can do and so on. The above description of the Maildir objects is very
simplified, it can do more things than that.

I hope this is sufficient as a starter.
        Bye,
        Milan
