wow darling you obviously didn't search your answer before asking your question. I've seen that answer so so many times lol
Go to Tools->Options->View->Autocomplete & untick that option & press apply. If you were using the new LW 4.9 beta you'd find it was an option rather than a choice.

Oh & you can right-click each search result tab so you can choose to close them or just clik the red cross.
