Sounds like something more complex. Do you see anything "junior" in there I 
maybe can help you with?

I think about picking up with this one first as a junior task.

Where would a good place for this be? In agent configuration Sandro pointed 
out (.config/akonadi/agent_config_akonadi_indexing_agent)? I bet thats handled 
by Akonadi itself and the agent can access it somehow?

I´d like to add three basic options to enable/disable

- mail indexing
- contact indexing
- note indexing

well, as one does usually not have many contacts or notes maybe just the mail 
indexing option would be enough.

I´d also like to check whether Akonadi search respects the setting whether a 
folder should be indexed or not. I have the impression that it doesn´t. It 
would be very helpful if I can just tell it to leave the huge LKML folders and 
some other folders alone for now.

I´d just create a branch to make these changes and then learn to stuff it into 
a review request with Phabricator once I got something workable? (My last 
review requests have been with Reviewboard still). Or maybe make two changes

1) Migrate the initialIndexing option

2) Then add mail indexing option

Thanks,
