 We ran a test to measure the impact of list size: we uploaded 90,000 vectors from Wikipedia dataset and then queried 10,000 vectors from the same dataset. The documentation recommends to use `lists` constant of `number of vectors / 1000`. In this case, it would be 90.

+But as our experiment shows, we can improve `select` speed if we increase lists (i.e. with more lists in the index we need to get less index data to get the same precision). So for 95% precision, we can take any of:
 
-- 3% of index data for 270 lists,
-- 6% - for 90 lists,
-- and 13% - for 30 lists.
+- 3% of index data = 270 lists
+- 6% of index data = 90 lists
+- 13% of index data = 30 lists
