How to search this blog

For reasons I don't fully understand, the little search box in the top left-hand corner does not work correctly. It returns no results when there are posts with the search term or it returns only some of the posts that contain the term.

What does seem to work is using Google's Advanced Search and specifying the domain name of my blog: Interestingly this only seems to work if you do NOT include the "www" at the beginning.

I'm so glad computers have made all our lives so much easier.
