elasticsearch - elasticsearch spring数据@query注释

Question

我正在尝试在Elasticsearch Spring数据中使用@query注释进行复杂查询，但是当我尝试以下简单查询时出现错误

@Query(value="{'bool':{'must':{'field':{'name':?0}}}}")
Segment findByName(String name);

在@Query批注中，您只需要使用转义的双引号而不是单引号:

@Query(value="{\"bool\":{\"must\":{\"term\":{\"name\":\"?0\"}}}}")
Segment findByName(String name);

另请注意，由于 field不是有效的查询，因此我已将 term替换为 match(或也可以使用 field)。
