Text configuration objects are supported for IQ (v15.2 and higher) and SQL Anywhere (v12 and higher) to control the creation of text indexes. PowerDesigner models text configurations as extended objects with a stereotype of <<TextConfiguration>>.
Text configurations contain a set of configuration settings that control the characteristics of text index data such as what terms to ignore, and the minimum and maximum length of terms to include in the index. Once you have created a text configuration, you can select it to control a text index on the Sybase tab of your text index property sheet (see Text Indexes).
You can modify an object's properties from its property sheet. To open a text configuration property sheet, double-click its Browser entry in the Text Configurations folder.
