Thus I do not know how it could be O(1).
  

       

~ O(1) is what I have observed through experiments with indexing of
several million documents.
     

What did you exactly measured? Just the time of the insert operation 
(incl. merge(), of course)? Was it a test on real documents?
   

I didn't really measure anything, I only observed this, as my focus was
something else, not performance measurements.
It is true that every time an insert/add triggers a merge operation,
things will slow down, but from what I recall (and this was about 1
year ago), the overall performance was steady as the index grew.
 

Try the same test with mergeFactor=2, you will see the difference.
