• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((nhieu tang) OR (chieu sang)) - hanh trung cap ((nhung luong) OR (nhung tuong)) dao van ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((nhieu tang) or (chieu sang)) - hanh trung cap ((nhung luong) OR (nhung tuong)) dao van ban*".
