[Koha-devel] Feasibility question

We're a small library with roughly 20,000 items. Our statewide digital consortium, however, provides access to a further 10,000 items (ebooks and downloadable audiobooks). We'd like to integrate records for these latter items into our catalog to facilitate access, but don't want search results to be overwhelmed with the downloadable, digital content. So ideally we'd like to be able to have searches default to our physical collection, with an option to include digital materials or to search the latter exclusively. Feasible?
