When using the search API, the field
commented_on_by.any) doesn’t behave like expected: it pulls up tasks liked by ALL people you give, not ANY.
e.g. Bob likes comment A, Alice liked B, Bob and Alice both liked C. The search for
liked_by.any=Alice,Bob will return only C.
It is important to note that it is coherent with the Advanced Search where the “liked by” field applies an (implicit) ALL operator. But the search, with an explicit
any being given, shouldn’t in my opinion.
