Search engines have a tough job.  There are literally millions of new pages going up on the internet daily.  Research reports indicate that even the largest search engines only cover about 20% of all the web pages.  Our preference is GOOGLE.CA, but even with this search engine, not everything is covered.  Also, the page you are looking for may not be listed under the keywords that you searched for.  Our suggestion is, if you can’t find it using a simple search, try using more specific key words.
