      It appears that Index Scan has a hidden initialization cost which somehow not revealed directly by our regression models but revealed indirectly by different values of the n_processed coefficient.

      Design an experiment where the queries selects different number of documents, like 10k, 20k, 30k,..., 150k, try to keep the same number of queries for every point
