What does the BoolFilterDesciptor.Should do compared to BoolFilterDesciptor.Must?

`query.Filter(f => f.Bool(boolFilter => boolFilter.Must(bf => bf.Field("MyField", "eq", "MyValue"))));`

compared to

`query.Filter(f => f.Bool(boolFilter => boolFilter.Should(bf => bf.Field("MyField", "eq", "MyValue"))));`

Sql translation for the bool filter:

- `Should` = `OR`
- `Must` = `AND`
- `MustNot` = `AND NOT`
