Sally - I have been seeing something similar, but it most definitely does not happen on all pages. For now, let me ask... are you searching your title quoted, or just a default all the words search?
And is your title including a list of keywords, say, rather than phrases in some sort of grammatical structure?
Also, if you add the extra word, is it a word that's included on your page? (I'm assuming so).
