Mostly my problem is that I don't use the UI properly. I hit return and don't select an option when they pop down. However, it does tend to come up with strange results:

Worbarrow Tout (has wikipedia page). If you are zoomed on the UK you get a selection of B&B's in the right general area.

Oxwich Burrows gives me a caravan park and a hall.

Both of these results have only one unambiguous meaning. Google gives me several results that are not correct.
