• Performing a fuzzy search may retrieve terms with similar spellings: ((ho trieu) OR (25 trieu)) tinh - hanh tinh ((toan nhung) or (doanh nhung)) duong manh toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho trieu) OR (25 trieu)) tinh - hanh tinh ((toan nhung) OR (doanh nhung)) duong manh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - hanh tinh ((toan nhung) or (doanh nhung)) duong manh toan cao".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - hanh tinh ((toan nhung) or (doanh nhung)) duong manh toan cao*.
