Where's Waldo?

I was hoping that I might be smart enough to locate student posts to the blog by typing in their names in the search box on the page which edit posts and displays the entries by title chronologically. I will give this another try in a minute, but as I struggled, I thought I'd make note of this. I am attempting to credit each student for last week's comments - either on paper or online- but the online part is taking me more check up time than I have. More later.
