• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (te sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve phan dau va hanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (te sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve phan dau va hanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (te sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve phan dau va hanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu cach) or (te sach)) tu ((hang xa) OR (hoang xa)) hoi. hieu ve phan dau va hanh vi cuu tre*.
