• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ty nang ma hoa. lieu va cam xuc va dinh ((((biet cua) OR (biet giua))) OR (viet ca)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ty nang ma hoa. lieu va cam xuc va dinh ((((biet cua) OR (biet giua))) or (viet ca)) te*".
