I had  a database, the main order entry table had 23 indexes on it. The
programmers insisted (and my manager backed them up) that they needed
to be able to search on first name of the customer or the recipient so
we needed two additional indexes on that.

Right, there's REAL selectivity on an index that includes entries like
"David" "Ann" "Susan"  "Michael"

uh huh... and I believe in the tooth fairy too
