The Loudoun County Public Schools (LCPS) site search, by default, returns results from content pages and files across the entire lcps.org domain (all LCPS sites), which might be from the district site, or from one of many subsites such as school sites.  It remembers the last option you chose (all or focused).

Focus Search Scope

To narrow the search scope to a particular school or LCPS department site, click the radio button to limit search to the site you're currently on.  Then enter your search terms and click the GO button.  To focus search on another school or department site, go to that site and click the Find-It-Fast button and focus your search on that site.
