That seems very odd.
Hmm.. It's enough to do 'select docid from documents where docid=0'
and I get 3 answers (3 rows).

Basically it's a simple web cms system with some kind of versioning.
Duplicate keys are created (probably) at updating the row.
After issuing an update op the row gets updated and new one with the
same data is created; ie. after an update all rows with the same docid
get same contents.
So, when doc is inserted I got one doc. After 1st update I get
(almost certainly) 2 rows, after 2nd update -- 3 rows, etc.

I'll try to investigate a little more on this but I'am very novice
