• Performing a fuzzy search may retrieve terms with similar spellings: tu cac ((thoi tang) OR (thoi trung)) luan hoi. hieu vu cau luc va hanh vi ((cua cu) or (sua chua))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cac ((thoi tang) OR (thoi trung)) luan hoi. hieu vu cau luc va hanh vi ((cua cu) OR (sua chua)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((thoi tang) OR (thoi trung)) luan hoi. hieu vu cau luc va hanh vi ((cua cu) or (sua chua))".
• Adding a wildcard symbol may retrieve word variants: tu cac ((thoi tang) OR (thoi trung)) luan hoi. hieu vu cau luc va hanh vi ((cua cu) or (sua chua))*.
