You can override the resource strings used by many of the built-in controls in your application resource bundle (as specified in faces-config.xml). This is usually the src\com\webMethods\caf\AppResources.properties file.
For example, add this key=value line to the resource bundle:
component.search-bar.tab.basic=Your Tab Text Here
That changes the text for all instances of the SearchBar control in your CAF application.
