The default search library setting determines what library is
searched from the advanced search screen and portal page by
default. Manual selection of a search library will override it. One
recommendation is to set the search library to the highest point you
would normally want to search.
The preferred library is used to show copies and URIs regardless
of the library searched. One recommendation is to set this to your
workstation library so that local copies show up first in search
results.
Focus this search tab by default when opening new catalog pages.
