• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hanh tang) OR (hanh mang)) ((cua tong) OR (cua nong)) thong va toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh tang) OR (hanh mang)) ((cua tong) or (cua nong)) thong va toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh tang) OR (hanh mang)) ((cua tong) or (cua nong)) thong va toan ban*.
