What does the term "Relevance" mean to the user in search results?

I am working on a project with search results, and questioning the use of the term "Relevance" to arrange the results. (In conjunction with price, a-z, etc).

Generally, we just use this term as the default search results order, but does the user understand what this means (even though from a technical standpoint we understand what it means)? Has it become ubiquitous enough now that it doesn't matter as much (i.e. Hamburger Menu)?

Is there a more user friendly and understandable term to use like Preferred, Best Match, Recommended, Default or Natural?

(Assume this is an overarching question and doesn't apply to a specific project, market, demographic).
