Hi Christian,
Because there's an OR in the WHERE clause. It simply doesn't work.
Currently. May be some future release brings something like skip - range
index scan:)
What about index fast full scan?

Why not consider using a concatenated index with
both columns versus writing the SQL statement as a
Union All
Because there's an OR in the WHERE clause. It simply doesn't work.
