KPeople will be performing the search and the aggregation. However, we though 
it might be best for it to install a Baloo Search Plugin since they can share 
the same search API.

KPeople can install its own search API if required.

The Email auto-completion database is currently created by the Baloo Email 
Indexer. Baloo provides an API to provide auto-completions.

KPeople currently does not have access to that database so it cannot do 
completion. KPeople's main job, IMO, is contact aggregation, and that is what 
we would like to use it for. It's just not obvious how to go about that.
 
In case you're interested, here is why it is slightly complex -

- The Email Contact completion db only contains "Name <email>" fields. It has 
no concept of Akonadi items / contacts.

- In order to aggregate the data one would have to search for the akonadi item 
which matches the "email". This akonadi item id would then be mapped to the 
higher level person id. One would then need to fetch all the contacts related 
to that person, aggregate the data and display it.

- "Fetching all the contacts related to that person" can be causing multiple 
trips to Akonadi, which could get slow.
