I am using the /search/person endpoint in the TMDB API to search for a person by name. When I make a query, the response includes a list of 20 people on the first page, and the total_pages property indicates there are more pages with additional results.

I tried making requests for all pages (up to the total number of pages) and aggregated the results into one array. After sorting all results by the popularity property, I compared the top 10 people from the first page of the initial response with the top 6 people from the sorted aggregated results.

I noticed that the two lists do not match. Could you clarify how the TMDB API distributes search results across pages? Are they sorted by relevance, popularity, or some other criteria?
