• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) y ((nang xa) or (dang xay)) hoi. hieu ve cam xuc van hanh lai chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y ((nang xa) OR (dang xay)) hoi. hieu ve cam xuc van hanh lai chau tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y ((nang xa) or (dang xay)) hoi. hieu ve cam xuc van hanh lai chau tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) y ((nang xa) or (dang xay)) hoi. hieu ve cam xuc van hanh lai chau tre*.
