Thanks. I wish I could do it without installing a new product.
Actually I could get the same effect but with a little bit of
hackiness. I added a `category` index which indexed
`_getCategoryForCatalog` method which can not be acquired
by subobjects because it start with `_`.

At any rate, either of these approaches solve half of the problem.
The other half is to do the same thing for a metadata. I doubt
it's easy to do that because unlike an index, metadata is not
plugable.
