Generates a stream of XML containing synonym information for the specified word.
The stream of XML is returned as a dtsStringHandle, which should be released once the calling program has extracted the text. The flags are a combination of the synonym-related SearchFlags used in dtsSearchJob.
Below is an example of the XML stream returned. Field order may vary and new fields may be added in future versions, so calling programs should not depend on the specific field layout in this example.
