Vandelay: Fix index-miss with MARC Imports using Match Sets

Vandelay: Fix index-miss with MARC Imports using Match Sets

In some Postgres installations, an expression such as:

(value LIKE '13423488%' OR value LIKE '245425%') will use a btree index,
but

value LIKE ANY('{13423488%,245425%}'::TEXT[])

will not.

Missing such an index can make matching incoming bibs based on a field
that's present in most of your existing records terrifically slow.
