Since there is a method that has vararg boolean argument,
we can remove this one. (same as Temporal, Number, ObjectId)

[jbl428]

I think it would be better to have a method of iterable arg version.

    /**
     * Value or values to search.
     * Value can be either a single value or an array of values of only one of the supported BSON types and can't be a mix of different types.
     *
     * @param value Values to search.
     */
    fun value(value: Iterable<Boolean>) {
        document["value"] = value
    }

we can have KProperty version of overload method.
this provide a user type-safety.

    fun path(path: KProperty<Boolean?>) {
        document["path"] = path
    }

    fun path(path: KProperty<Iterable<Boolean?>?>) {
        document["path"] = path
    }

[jbl428]

If we have Kproperty path method. we can replace this line

path(Customers::name)

@jbl428 Applied comments! Thank you for the kind guide, and I'm sorry for the late change.

[jbl428]

Thank you for contribution.
I will handle the reviews after PR is merged :)

[jbl428]

limit stage is now implemented, so we can use limit function

[jbl428]

I think that the param type should be KProperty<String>
