Sometime recently, Google seemed to have dropped all search suggestions for a keyword plus the word are.
A Google Web Search Help thread reported that the words [jews are] no longer brings up any search suggestions as you type. So the searcher asked, "Are certain suggestions removed?" So I tried a bunch I knew did bring up things in the past, such as Chinese are..., Blacks are...., Muslims are... and nothing came up.
It does seem like Google decided to drop the X are type of search suggestions, which may be a smart move.
