Another Quandry: The + Operator (Score 2, Informative)

From what I recall and the way things seem to work now, the + operator has been changed slightly.

By default, words like "to" "with" and "by" are not included in a search because they are deemed too common. However, I used to be able to force inclusion of those common words using the + operator.

Now it seems that this is no longer possible. That is, the strings one +to another and one +for another give the same results (without quotes). In fact, the + is replaced by a space in the above queries and that definitely didn't used to be the case.

Does anyone else remember the good ole' + operator?
