&
Finds webpages that contain all the terms or phrases in a query. Same as AND and &&.
Example
foo & bar
foo& bar
foo &bar
Remarks
Each of the examples is equivalent to foo AND bar. Note, however, that foo&bar is equivalent to “foo bar”. This is because, when no spaces are present, & functions as a stopword, that is, a character that terminates a word. Bing Wordbreaker functionality then removes &.
