Sybase IQ text configuration objects and TEXT indexes using external libraries have limitations by design.
For TEXT indexes on binary columns, you must use external libraries provided by external vendors for document conversion. Sybase IQ does not implicitly convert documents stored in binary columns.
N-gram based text searches are not supported if an external term-breaker is used to tokenize the document.
You cannot use external libraries to create TEXT indexes on SQL Anywhere tables; doing so results in an error.
