• Performing a fuzzy search may retrieve terms with similar spellings: te sach tay lang ha hoi. ((hieu va) OR (hieu qua)) co luc gia ((thanh vi) or (thanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tay lang ha hoi. ((hieu va) OR (hieu qua)) co luc gia ((thanh vi) OR (thanh va)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tay lang ha hoi. ((hieu va) OR (hieu qua)) co luc gia ((thanh vi) or (thanh va)) cua tre*".
