• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang ma hoi. hieu ve cam ((loc va) or (hoc va)) ((thanh vi) OR (thanh va)) cua vat~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu ve cam ((loc va) OR (hoc va)) ((thanh vi) OR (thanh va)) cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. hieu ve cam ((loc va) or (hoc va)) ((thanh vi) OR (thanh va)) cua vat".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ma hoi. hieu ve cam ((loc va) or (hoc va)) ((thanh vi) OR (thanh va)) cua vat*.
