All of them are related and there is no separating them. IN levels are able to influence the mechanism of searching in the matrix, and how many results will be returned from the parameter. Knowing what are the connections between those three concepts You may create any parameter, from the very simplest ones to advanced parameters where the searching mechanism and OUT levels parameter setting are able, not only to select and order results but even evaluate other elements in Hyperon Studio and use pulled results.
