• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky dang ma hoi. hieu ve cham xuc ((((va hanh) OR (van hanh))) or (va dinh)) thai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky dang ma hoi. hieu ve cham xuc ((((va hanh) OR (van hanh))) OR (va dinh)) thai cua viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky dang ma hoi. hieu ve cham xuc ((((va hanh) OR (van hanh))) or (va dinh)) thai cua viet*".
