If a search returns zero results then the page indicates that you are viewing
"1-0 of 0" results and a single blank result is displayed.
To replicate, enter a word that returns no results, e.g. 'plumboozle' into the
search box and click 'search'.
I tested this on Wikipedia, Wiktionary and Commons with a couple of different
terms, and all exhibited this behaviour.
