• If you are trying to use Boolean operators, they must be ALL CAPS: hoc viet trung - ((hanh han) OR (hanh nhan)) cua nhin trong dan ((phan tap) OR (han tap)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc viet trung - ((hanh han) OR (hanh nhan)) cua nhin trong dan ((phan tap) or (han tap))".
• Adding a wildcard symbol may retrieve word variants: hoc viet trung - ((hanh han) OR (hanh nhan)) cua nhin trong dan ((phan tap) or (han tap))*.
