I noticed the search function I had installed previously did not search the full text of the whole blog. It searched the headings only, which is not nearly good enough.
I've installed a new function which searches all the text on the blog, including the body of the postings. If you search for 'Dairy Queen' or 'Ray Barton,' you should find all the postings containing those phrases.
I'll keep an eye on this to make certain it works properly.
