• Performing a fuzzy search may retrieve terms with similar spellings: vu ((sach ky) OR (sach ty)) sang tai hai. hieu va cac ((xuc va) or (duc va)) danh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((sach ky) OR (sach ty)) sang tai hai. hieu va cac ((xuc va) OR (duc va)) danh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((sach ky) OR (sach ty)) sang tai hai. hieu va cac ((xuc va) or (duc va)) danh vi cua te*".
