Sybase IQ text configuration objects and TEXT indexes have these limitations by design:
Sybase IQ engine does not provide support for TEXT indexes spanning multiple columns.
TEXT index manual refresh or automatic refresh options are not supported.
sp_iqrebuildindex cannot be used to build TEXT indexes.
You cannot create TEXT indexes within BEGIN PARALLEL IQ…END PARALLEL IQ.
The NGRAM term-breaker is not supported for TEXT indexes. Sybase IQ currently only supports the GENERIC term-breaker and one TEXT index per column.
