> The Tuning Guide topic "Create useful indexes" (http://db.apache.org/derby/docs/10.10/tuning/ctundepth1002853.html)
has the following excessively vague note at the end:
> "Note: Derby does not support indexing on columns with data types like BLOB, CLOB, and
> The topic also has a cross-reference to the "CREATE INDEX statement" topic in the Derby
Reference Manual, but that topic says nothing about data type limitations for index columns.

> In an email exchange, Knut says that LONG VARCHAR and user-defined types should be added
to make the list complete, but he also suggests moving this information from the tuning guide
to the "CREATE INDEX statement" topic in the Reference Manual, since we already reference
that topic and since the information needs to be there.
