java - ElasticSearch Java API 搜索错误

Question

每个 searchRequest.toString() 和每个错误信息。

我认为，如果您在检查那些搜索正文和错误之前看到底部的摘要，应该更容易理解我的问题。

    }
}

}

这个没有错误。

现在，总结。

无论我在 "term": {"2474": [ "20", "17"]} 处使用 should 还是 must。

当我在查询正文中设置 "term": {"2474": [ "20", "17"]} 时总是出错。

一旦我从查询正文中删除 "term": {"2474": [ "20", "17"]} ，它就可以正常工作。

为什么？

Answer 1

术语查询只需要一个值。术语意味着多个值。尝试像这样

 "terms" : {"2474" : [ "20", "17" ]}

将术语查询更改为术语..请参阅以下网址, http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-common-terms-query.html
