Understanding certain key concepts, such as supported document

of DB2® Text Search.
DB2 Text Search security overview
DB2 Text Search
executes administrative operations based on the authorization ID of
the user executing the operation. Different to previous releases,
there is no prerequisite for database privileges for the instance
owner anymore, and it is not necessary for the fenced user to be in
the same primary group as the instance owner.
DB2 Text Search capacity planning and optimization
A number of factors influence
performance and resource use in DB2 Text
Search. When planning system capacity for DB2 Text Search, consider the query workload,
the number of parallel index updates, the expected size and growth
rates of your text indexes, and the processing time for the documents
you are indexing.
