What is the best way to filtering in API?

[Cem Topkaya]

Let's say we need to filter data behind of the API.

Which semantic is useful to naming filter functions.

IEnumerable<XElement> filterByName(string name)
List<XElement> filterByLessonCode(string code)

or

XElement[] filterByCriteria(string fieldName, string term)

Would you please explain which one these your something else should be used?
