• Performing a fuzzy search may retrieve terms with similar spellings: tu san kho tang ((ha hoi) OR (xa hoi)). hieu ve ((chat xuc) or (chao xu)) van hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu san kho tang ((ha hoi) OR (xa hoi)). hieu ve ((chat xuc) OR (chao xu)) van hanh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san kho tang ((ha hoi) OR (xa hoi)). hieu ve ((chat xuc) or (chao xu)) van hanh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: tu san kho tang ((ha hoi) OR (xa hoi)). hieu ve ((chat xuc) or (chao xu)) van hanh vi cua tre*.
