• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((sach tu) OR (sach ty)) tang lai hoi. hieu van ((cham soc) or (cam lo)) va hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((sach tu) OR (sach ty)) tang lai hoi. hieu van ((cham soc) OR (cam lo)) va hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((sach tu) OR (sach ty)) tang lai hoi. hieu van ((cham soc) or (cam lo)) va hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: thuat ((sach tu) OR (sach ty)) tang lai hoi. hieu van ((cham soc) or (cam lo)) va hanh vai cua te*.
