This screen displays all the Pages that you have access to that also have the
"Include in Search" option selected.
Searchable Pages will be searched by the built-in Site Search and displayed on the
Search Results Page if a match is found.
NOTE: Only Pages that the searcher has "view" access to will be displayed in the
search results, so it is safe to enable this Page option with Membership and Private
Pages.
To include a Page in the Site Search, edit the Page's Properties and select the
"Include in Search" option.
