• Performing a fuzzy search may retrieve terms with similar spellings: ((tu san) or (tu sanh)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van han tai cuc tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu sanh)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van han tai cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (tu sanh)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van han tai cuc tre".
• Adding a wildcard symbol may retrieve word variants: ((tu san) or (tu sanh)) ky nang o lai. hieu ve ((cac xuc) OR (cac nuoc)) van han tai cuc tre*.
