• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - ((hanh tung) OR (anh tang)) cua thong hong anh ((tuan tu) OR (tuan thu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - ((hanh tung) or (anh tang)) cua thong hong anh ((tuan tu) OR (tuan thu))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - ((hanh tung) or (anh tang)) cua thong hong anh ((tuan tu) OR (tuan thu))*.
