请求体:

字段 默认值 含义
filter {}(全部) 文档必须满足的条件。
limit 1 返回的文档数量。-1 返回全部。
skip 0 先跳过的匹配文档数,用于分页。
index 无 使用 索引 响应查询。

没有任何匹配时,返回 204 No Content,响应体为空。

过滤器

过滤器是一个 JSON 对象。每个字段是一个条件,所有条件都必须满足。

等于某个值:{"plan": "pro", "country": "GB"}。

运算符 字段满足条件时匹配 示例
$eq 等于该值 {"plan": {"$eq": "pro"}}
$ne 不等于 {"plan": {"$ne": "free"}}
$gt 大于 {"mrr": {"$gt": 100}}
$ge 大于或等于 {"mrr": {"$ge": 100}}
$lt 小于 {"mrr": {"$lt": 100}}
$le 小于或等于 {"mrr": {"$le": 100}}
$in 是其中一个值 {"plan": {"$in": ["pro", "team"]}}
$nin 不是其中任何一个值 {"country": {"$nin": ["US", "GB"]}}
$contains 是包含该值的文本 {"email": {"$contains": "@example.com"}}

请使用这些确切的名称:$ge 和 $le,而不是 $gte 和 $lte。使用不存在的运算符的过滤器不会匹配任何文档。

以 ISO 格式文本存储的日期("2026-10-28T09:30:00Z")按时间顺序比较:{"created_at": {"$gt": "2026-01-01"}}。

没有索引时,文档不按任何特定顺序返回。要得到有序结果,或让大集合上的查询更快,请使用 索引。

在控制台中试用

控制台 会在你输入时运行过滤器,提示你数据中的字段名,并根据数据给出示例过滤器。Schema 标签页列出每个字段的类型和最常见的值。
