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