Create default filter by space in Confluence

[William Harry Spagnola]

Is there a way to set up the search in Confluence, so that it automatically filters by a default space.  I work at a large university but I only use Confluence for my particular research organization.  Consequently, if I don't filter by space, it is very difficult to find anything I am looking for.  However,  it gets annoying clicking the button every time I want to restrict the search to just our organization.

Thanks for the help.  I've included a screenshot of what I want to happen by default.
