[BUG] TypeError error when using a .filter(...) on a Search object.

[Godefroy-Amaury]

What is the bug?

Get a TypeError error when using a .filter("terms", ...) on a Search object.

How can one reproduce the bug?

Having a str instead of an int for Bool.filter or Bool.must attributes when reach the Bool.__and__ method.
This case can happen when using string based percent (eg: "50%") instead of pure integer (eg: 50) for minimum_should_match.

What is the expected behavior?

Accept 50, "50" or "50%" as valid values.

Do you have any additional context?

A TODO statement is present in the code for this specific case.
This TODO statement date back at least from the opensearch-dsl 1.0.
