• If you are trying to use Boolean operators, they must be ALL CAPS: ho lieu tinh - thanh ((trung va) OR (truong va)) nhung cong ((dan toan) OR (dan chan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - thanh ((trung va) OR (truong va)) nhung cong ((dan toan) or (dan chan)) cao".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - thanh ((trung va) OR (truong va)) nhung cong ((dan toan) or (dan chan)) cao*.
