How can I randomize search results in Views?
Results are displaying in ascending order because you may have another sort criteria present above Global: Random (asc) like say Content: Post date (desc).

Solution: Move Global: Random (asc) sort criteria to top. Surely it will work.


  Note: If you have more than one sort criteria lets say 3, then results
  first get sorted with first criteria then with second and then with
  third.
