• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang x) or (tang van)) hoi. ((hieu van) OR (hieu va)) cac toc va hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang x) OR (tang van)) hoi. ((hieu van) OR (hieu va)) cac toc va hanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang x) or (tang van)) hoi. ((hieu van) OR (hieu va)) cac toc va hanh vi cua tre*".
