As you prepare your topic design, consider the naming conventions you will use. Your topic names should help identify the subject matter of the kinds documents you want to find.
To ensure the best search performance, use alphanumeric characters (A through Z, and 0 through 9) for topic names. You can also use foreign characters whose ASCII value is greater than or equal to 128, as well as these symbols: $ (dollar sign), % (percentage sign), ^ (circumflex), + (plus sign), - (dash), and _ (underscore). Using other nonalphanumeric characters, may cause misinterpretation of the topic name and affect results.
