The "Search" menu on this site will lead you to articles published through the current (Joomla) system. Unfortunately, the search will not work for PDF files or other "foreign" data. To get a different and possibly more comprehensive search, you can create a new browser window to search on Google (or your other favorite search engine).
For example, try the following on Google:
<your text of interest> -site:ewingfamilyassociation.org
replacing the <...> content with your particular search request.
We hope to add a more comprehensive site indexing and search in the future.
