Using the new Baloo engine is great. However in the search window when I search e.g. "To" for "someName" in all folders (I have mails only in maildir), it tells the "7 matches" but in fact the list shows 13 mails (In general: it often show more mails in the list than what the number of matches tells).
Checking the list reveals that some mails show twice, where in fact inside the folder the mail really only exists once.
Interesting is, when I click a second time on the "Search" button inside the still open search window, then the list is reduced and now only shows the number of matched mails (but now the number of matches at the left bottom is replaced with "Search complete."  - which seems to be probably a different bug as it always should tell me the number of matches)

Reproducible: Always
