• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu lang) OR (chieu sang)) - hanh tinh cua nhung ((nong vinh) OR (nang vinh)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu lang) OR (chieu sang)) - hanh tinh cua nhung ((nong vinh) or (nang vinh)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu lang) OR (chieu sang)) - hanh tinh cua nhung ((nong vinh) or (nang vinh)) toan tap*.
