                WhereCondition cond2,
                WhereCondition... condMore)

Creates a WhereCondition by combining the given conditions using OR. The returned WhereCondition must be used inside where(WhereCondition, WhereCondition...) or whereOr(WhereCondition, WhereCondition, WhereCondition...).
