• If you are trying to use Boolean operators, they must be ALL CAPS: su ((tai cao) OR (tai sao)) tang xa hoi. hieu ((ve cam) OR (ve cac)) duc va nhanh quang cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((tai cao) or (tai sao)) tang xa hoi. hieu ((ve cam) OR (ve cac)) duc va nhanh quang cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((tai cao) or (tai sao)) tang xa hoi. hieu ((ve cam) OR (ve cac)) duc va nhanh quang cua tre*.
