As a stop gap measure, we are using Google's custom search engine service.

I guess this all goes back to the decision in DDS not to support
arrays in records. The argument goes that arrays should be
implemented in tables, not within individual rows, in a relational
database (ignoring the fact that some RDBMS's do allow arrays within
rows).
So the question becomes, should a programming language make it easy
to get around a design limitation in the database? One problem is
that any workaround (easy or not) is fraught with certain dangers.
For example, if the field layout happens to change, the overlay may
become invalid.
The bottom line is that if EXTNAME suits your purposes better than
LIKEREC, then continue to use it.
