• If you are trying to use Boolean operators, they must be ALL CAPS: chao thu bang - ((ganh nang) OR (anh bang)) van nhung cong ((manh toan) OR (tinh toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao thu bang - ((ganh nang) or (anh bang)) van nhung cong ((manh toan) OR (tinh toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: chao thu bang - ((ganh nang) or (anh bang)) van nhung cong ((manh toan) OR (tinh toan)) tap*.
