goog drop plus
that's not "goog plus" but the goog search "plus operator" and have replaced it with "goog verbatim"
in the past, we provided users with the “+” operator to help you search for specific terms. However, we found that users typed the “+” operator in less than half a percent of all searches, and two thirds of the time, it was used incorrectly. A couple of weeks ago we removed the “+” operator, encouraging the use of the double quotes, which are more likely to be used correctly.
