• If you are trying to use Boolean operators, they must be ALL CAPS: ho lieu tinh - thanh cong luan dung ((trong thanh) OR (rong thanh)) ((khan cap) OR (thanh cac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - thanh cong luan dung ((trong thanh) OR (rong thanh)) ((khan cap) or (thanh cac))".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - thanh cong luan dung ((trong thanh) OR (rong thanh)) ((khan cap) or (thanh cac))*.
