When is a CTXCAT index NOT suitable?

Answer: There are differences in the time and space needed to create the index. CTXCAT indexes take a bit longer to create, and they use considerably more disk space than CONTEXT indexes. If you are tight on disk space, consider carefully whether CTXCAT indexes are appropriate for you.

With query operators, you can use the richer CONTEXT grammar in CATSEARCH queries with query templates. The older restriction of a single CATSEARCH query grammar no longer holds.
