Blogs Directory Not Searching Titles

I just updated to Blogs Directory 1.1.5 and was excited to see in the changelog that search results now include keywords in blog titles. But this is clearly not working with our directory at http://tripawds.com/blogs

At the top of our directory page, you will notice a number of our "featured blogs" but when searching for words in the titles of these blogs no results are returned. Example: Searching for "Nutrition" returns no results but searching for "supplements" does. Nutrition is in the title and supplements is in the description of our Nutrition blog.

Does it take a certain amount of time for all sites to be indexed? All the sites I mention are public, and I have not selected either of the new "hide" options. Is there something else I'm missing?
