Our relevance search does not take into account views or pagerank. And to add complication, views in all time can get really high skewing stuff so we probably would need views by year or something to correct for that.
But… with pagerank / accounting for view counts / likes it is possible we can come up with a far better relevance algorithm.
This is complex stuff, a multi trillion dollar company was built on these ideas and another multi trillion dollar company has no easy way catching up.
