这些关键字允许开发人员指定要返回的结果的页码、要跳过的结果数以及要返回的结果数。通过使用这些关键字，开发人员可以轻松地创建分页查询，而无需手动指定分页参数。

Repository query keywords

Supported query method subject keywords

下表列出了 Spring Data 存储库查询派生机制通常支持的主体关键字，以表示谓词。有关受支持关键字的确切列表，请查阅特定存储区的文档，因为此处列出的某些关键字可能在特定存储区中不受支持。

The following table lists the subject keywords generally supported by the Spring Data repository query derivation mechanism to express the predicate. Consult the store-specific documentation for the exact list of supported keywords, because some keywords listed here might not be supported in a particular store.

Table 1. Query subject keywords
Keyword	Description
`find…By`, `read…By`, `get…By`, `query…By`, `search…By`, `stream…By`	General query method returning typically the repository type, a `Collection` or `Streamable` subtype or a result wrapper such as `Page`, `GeoResults` or any other store-specific result wrapper. Can be used as `findBy…`, `findMyDomainTypeBy…` or in combination with additional keywords.
`exists…By`	Exists projection, returning typically a `boolean` result.
`count…By`	Count projection returning a numeric result.
`delete…By`, `remove…By`	Delete query method returning either no result (`void`) or the delete count.
`…First<number>…`, `…Top<number>…`	Limit the query results to the first `<number>` of results. This keyword can occur in any place of the subject between `find` (and the other keywords) and `by`.
`…Distinct…`	Use a distinct query to return only unique results. Consult the store-specific documentation whether that feature is supported. This keyword can occur in any place of the subject between `find` (and the other keywords) and `by`.

In addition to filter predicates, the following list of modifiers is supported:

Table 3. Query predicate modifier keywords
Keyword	Description
`IgnoreCase`, `IgnoringCase`	Used with a predicate keyword for case-insensitive comparison.
`AllIgnoreCase`, `AllIgnoringCase`	Ignore case for all suitable properties. Used somewhere in the query method predicate.
`OrderBy…`	Specify a static sorting order followed by the property path and direction (e. g. `OrderByFirstnameAscLastnameDesc`).
