在JavaScript中的查询正文中使用Elasticsearch后终止 [英] Using elasticsearch terminate after in query body in javascript

问题描述

我正在尝试只为查询返回一个结果，我知道该查询可能返回多个结果，所以我想使用terminate_after参数，但是我无法弄清楚如何在查询主体中使用它在javascript中.我尝试将其放在正文中，如下所示，但我得到了 parsing_exception :"[terminateAfter]中VALUE_NUMBER的未知键."

I am trying to get only one result back for a query I know may return more than one result, so I would like to use the the terminate_after parameter, but I can't work out how to use it in a query body in javascript. I have tried putting it in the body, like below, but I get a parsing_exception: "Unknown key for a VALUE_NUMBER in [terminateAfter]."

client.search({
    index: 'myindex',
    type: 'mytype',
    body: {
        terminateAfter: 1,
        query: {
            term: {
                searchField: searchString
            }
        }
    }
}, function(error, results){}

我也尝试将其放入查询中，但这也会导致 parsing_exception :"[terminateAfter]查询格式错误，查询名称后没有start_object"

I have also tried putting it inside the query, but this also causes a parsing_exception: "[terminateAfter] query malformed, no start_object after query name"

我正在使用Elasticsearch 5.3版本和elasticsearch npm模块的13.3.1版本.

I am using version 5.3 of elasticsearch and version 13.3.1 of the elasticsearch npm module.

推荐答案

您几乎完全正确， terminateAfter 应该放在 body 之外，如下所示:

You've almost got it right, terminateAfter should go outside the body, like this:

client.search({
    index: 'myindex',
    type: 'mytype',
    terminateAfter: 1,
    body: {
        query: {
            term: {
                searchField: searchString
            }
        }
    }
}, function(error, results){}
