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