Hi,

Baloo does not index contact UID, so you won't get any matches :-)

If you only want to search by UID, you can use GID fetch. GID is identifier of 
content of the item (UID for vCards, UID for iCals, Message-Id for emails, 
etc), which is stored directly in Akonadi.

You can use regular ItemFetchJob to fetch items by GID:

Item item;
item.setGid("Kp9LZPRW8P");
ItemFetchJob *fetch = new ItemFetchJob(item, this);
...
...

Since GID is not guaranteed to be unique, you might want to use 
fetch->setCollection() to specify from which collection to fetch (it also 
speeds up the lookup a lot) if you work only with one collection.
