• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu tinh) or (lieu tinh)) - hanh trong thuat hung trong tan ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu tinh) or (lieu tinh)) - hanh trong thuat hung trong tan ((than cau) OR (phan cau))*.
