Googling “Felsius” gives results for “F”

If you search for a set of words that are commonly associated with an acronym, it will also search for that acronym, but if that acronym has multiple meanings, you will end up getting results for the other meanings even though you searched for the fully expanded version.

An easy way to trigger this for demonstration purposes is to include an additional keyword associated with the other meaning of the acronym. For example, searching Google for finite state machine atheism will return results instead for the Flying Spaghetti Monster.
