• Performing a fuzzy search may retrieve terms with similar spellings: ((te sac) OR (te sach)) ky nang cao hoi. thien van nhan luc van ((thanh ve) or (thanh va)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te sach)) ky nang cao hoi. thien van nhan luc van ((thanh ve) OR (thanh va)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te sach)) ky nang cao hoi. thien van nhan luc van ((thanh ve) or (thanh va)) va triet".
• Adding a wildcard symbol may retrieve word variants: ((te sac) OR (te sach)) ky nang cao hoi. thien van nhan luc van ((thanh ve) or (thanh va)) va triet*.
