I believe that this is not the point, since this change did not change the results at all. In fact, the search has to understand that when looking for “beneficios abobora” it has to look for titles that have the 2 words, before any other result. So it can’t show a result for example “beneficios do cogumelo” before showing all titles that have “beneficios” and “abobora” in the title before.
