• Performing a fuzzy search may retrieve terms with similar spellings: thu sach tu ((nano va) or (tao cau)) hoi. hieu ve chat ((xuc va) OR (luc va)) danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach tu ((nano va) OR (tao cau)) hoi. hieu ve chat ((xuc va) OR (luc va)) danh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach tu ((nano va) or (tao cau)) hoi. hieu ve chat ((xuc va) OR (luc va)) danh vi cua te*".
