问题描述

而不是在以下查询中使用 dis_max ，我想查找两个 more_like_this 查询的总和。如何修改此查询才能实现？

Instead of using dis_max in the following query, I want to find the sum of two more_like_this queries. How can I modify this query to achieve that?

推荐答案

通过<一个href =https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html =nofollow> bool 查询使用应该子句

示例：

 "query": {
    "bool": {
      "disable_coord" : "true",
      "should": [{
        "more_like_this": {
          "fields": [
            "PRIMARY_CONTENT_EN"
          ],
          "ids": [
            173161
          ],
          "min_term_freq": 1,
          "max_query_terms": 2,
          "boost": 1
        }
      }, {
        "more_like_this": {
          "fields": [
            "PRIMARY_CONTENT_EN"
          ],
