• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh ((tang cua) OR (trung tuan)) nhung cong tap ((hoa cau) OR (hoa mau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh ((tang cua) or (trung tuan)) nhung cong tap ((hoa cau) OR (hoa mau))~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - hanh ((tang cua) or (trung tuan)) nhung cong tap ((hoa cau) OR (hoa mau))*.
