• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang cao hoi. thien van ((nam luc) OR (nam thuc)) van ((thanh ve) OR (thanh va)) cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang cao hoi. thien van ((nam luc) OR (nam thuc)) van ((thanh ve) or (thanh va)) cua viet".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang cao hoi. thien van ((nam luc) OR (nam thuc)) van ((thanh ve) or (thanh va)) cua viet*.
