Seems to work to me. Check at the end of that page and I see "given the size of the vocabulary used in this library really is three hundred and twenty words that big is a list of these three hundred and twenty words available". If you are referring to the whole page being in bold, that happens because you are looking up for that page exactly. Use the "string only" search if you want a location string for a particular sentence, to preserve the bold around that sentence. The issue with that is that it will give you a different page (although still containing that string). E.g:
