• Performing a fuzzy search may retrieve terms with similar spellings: ((te cac) OR (te cao)) ky lang ha hoi. hieu va ((tham loc) or (tham nuoc)) va hanh di cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ky lang ha hoi. hieu va ((tham loc) OR (tham nuoc)) va hanh di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) OR (te cao)) ky lang ha hoi. hieu va ((tham loc) or (tham nuoc)) va hanh di cua te".
• Adding a wildcard symbol may retrieve word variants: ((te cac) OR (te cao)) ky lang ha hoi. hieu va ((tham loc) or (tham nuoc)) va hanh di cua te*.
