Courts do not require a literal monopoly before applying rules for single firm conduct; that term is used as shorthand for a firm with significant and durable market power — that is, the long term ability to raise price or exclude competitors. That is how that term is used here: a "monopolist" is a firm with significant and durable market power.

Since search engines are all free to use, many of the criteria of a monopoly seem hard to apply, but the classic defintions I'm familiar with include things such as "no reasonable substitute" which is not the case for Google Search.
