• Performing a fuzzy search may retrieve terms with similar spellings: co sach thieu ((tang van) OR (trong van)) hoe. hieu va ((cham xuc) or (chat xuc)) va hanh vi cua cu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: co sach thieu ((tang van) OR (trong van)) hoe. hieu va ((cham xuc) OR (chat xuc)) va hanh vi cua cu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach thieu ((tang van) OR (trong van)) hoe. hieu va ((cham xuc) or (chat xuc)) va hanh vi cua cu".
• Adding a wildcard symbol may retrieve word variants: co sach thieu ((tang van) OR (trong van)) hoe. hieu va ((cham xuc) or (chat xuc)) va hanh vi cua cu*.
