ECMA-402 sensitivity maps to a combination of CollatorOptions strength and case_level. ECMA-402 usage: "search" means -u-co-search which is of very, very questionable utility considering that neither ECMA-402 nor ICU4X has API surface for prefix or substring matches.

These things should be explained in the docs for CollatorOptions. See #4525 (comment)
