Is it possible to create a search card with a search field that will search two variables in an "OR" situation?

We have two "Description" fields from our legacy system. One is short (30 characters) while the other is long (144 characters). These two fields have not been used consistently and many cases the long description field is empty or contains total different information than the short description. I would like a search form that would have a single description field that will search both of the description fields.

So the user could search for "Bracket" and get a hit if either fields contain it.
