org.bson.json.JsonParseException: JSON reader 期待一个值但发现 ':' - Mongo springboot 中的查询抛出此错误

Question

我正在尝试获取在给定字段中具有匹配字符串的所有记录。

    @Query('''{$match:
                { $or :
                        [
                            'name' : { $regex: ?0, $options:'i' },
                            'displayName' : { $regex: ?0, $options:'i' },
                            'url' : { $regex: ?0, $options:'i' } 
                        ]
                }
               }''')
    Page<Project> findAllByNameOrSeoNameOrDomainNameOrUrl(String searchString, Pageable pageable)

我正在提供此查询，但它抛出了错误。知道我做错了什么吗？以及如何修复它？

我弄错了。我在做什么。 $or 中缺少大括号 {}。也不需要像@prasad_ 在评论中所说的那样 $match。

@Query('''{ $or :
                        [
                            {'name' : { $regex: ?0, $options:'i' }},
                            {'displayName' : { $regex: ?0, $options:'i' }},
                            {'url' : { $regex: ?0, $options:'i' }} 
                        ]
                }
               ''')
