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