ability to link queries with OR not just AND

Use case

I have a DB where EntryA has one-to-many relationships with EntryB.
I encountered a case where I have a text field, and I want to query the EntryA database to retrieve all entries filtered by that text field's value.
So for value 'aa', I want to get all the EntryA values where EntryA.name contains 'aa' OR(not AND, which is the default) if EntityA.items contain items with name containing 'aa'

Code example

        final builder =
            store.box<EntryA>().query(EntryA_.name.contains('aa'))
              ..link(EntryA_.owner, Owner_.id.equals(123))
              ..backlink(EntryB_.parent, EntryB_.name.contains('bb'));

从查询入口 store.box<EntryA>().query(...) 开始，检查所示的 link 和 backlink 约束是如何组合的。定义 EntryA.name.contains('aa') 与匹配的相关项之间的 OR 应如何工作，然后通过一个针对性查询示例验证其行为。当查询能够表达所请求的 OR 关系，而不是仅应用 AND 语义时，即表示完成。
