• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh dung cua thong hoang van ((((luan ban) OR (luan han))) OR (van ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh dung cua thong hoang van ((((luan ban) OR (luan han))) or (van ban))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh dung cua thong hoang van ((((luan ban) OR (luan han))) or (van ban))*.
