53 results in total. Shows first 50. press more. Only 2 more appear because we remove duplicates.

Removing duplicates can make sense because we do not use a scroll token, so when data change as it do all the time, then the record position can change. But it should still show 53 results. So something fails in the pagination.
I'm not sure if it is related to the free text query (when no q param we sort, else it is by score).
