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