For example lets say my main keyword was "how to" but I wanted to "include" searches for new and iphone in "how to" I was able to get long tail keywords that included both new and iphone only. Now with the new change when I add new,iphone it gives all search results that have either iphone or new but not together in whatever order like it did. This change is confusing because I would like to find just keywords that have my prime keyword: how to along with iphone and new and now I can no longer do that.
