Oh, it's happened to me too. And sometimes it replaces one term with another word with similar spelling but not related at all, the typed term is still in the textbox, but the terms bolded in the summary are different. It started a little after the anti-content-farms changes where applied, so I thought it was some temporary glitch. I haven't seen it recently, but maybe it's because I'm not making complex queries since.
