AO Global Search is quite remarkable. Anglicans Online lists links to 5000 web sites that have some Anglican content or relevance. Our Full Search looks in all 33000 of those pages for you. But no farther. A global search engine like Alta Vista finds 1630 web pages.
All search engines work in two phases.
The first phase builds an index in one place, and the second phase answers search requests by looking in that index. When you request a search, it is not actually hunting around the Internet at that time. It has already done the hunting, and stored the results. Your search requests are being looked up in an index that resulted from a systematic scan of web pages. The index of Anglicans Online itself is rebuilt each week just after Anglicans Online is published, so it is always completely current.
