If search returns no results, suggest Link+
If a patron searches Vega and gets zero results, can the results page say something like, "Can't find what you're looking for? Try Link+"
See an example from another library's catalog that does this.

The Link+ button is hard for patrons to find. We want out patrons to be empowered to search Link+ by being pointed to it before they get frustrated with their search.
