Question

我正在尝试链接多个match_phrase_prefix查询，但是由于某种原因，它不会返回任何结果（也没有错误）。当我尝试的时候一个match_phrase_prefix一切正常。我使用的是弹性搜索版本2.3，我的查询如下所示：

"query": {
    "bool": {
        "must": [
            {
                "match_phrase_prefix": {
                    "title": "נפ"
                }
            },
            {
                "match_phrase_prefix": {
                    "sub_title": "נפצ"
                }
            }
        ]
    }
}

我对特定索引的映射是：

{
"wcm_articles": {
  "mappings": {
     "article": {
        "properties": {
           "approved_talkbacks_counter": {
              "type": "integer"
           },
           "article_link": {
              "type": "string",
              "index": "not_analyzed"
           },
           "author": {
              "type": "string",

           },
           "category_id": {
              "type": "string",
              "index": "not_analyzed"
           },
           "date_updated": {
              "type": "date",
              "format": "date_hour_minute_second"
           },
           "is_old": {
              "type": "boolean"
           },
           "is_promoted": {
              "type": "boolean"
           },
           "is_video": {
              "type": "boolean"
           },
           "last_update_user": {
              "type": "string",
              "index": "not_analyzed"
           },
           "launch_date": {
              "type": "date",
              "format": "date_hour_minute_second"
           },
           "plain_text": {
              "type": "string",
              "analyzer": "hebrew"
           },
           "promotion_notes": {
              "type": "string",
              "index": "not_analyzed"
           },
           "status": {
              "type": "string",
              "index": "not_analyzed"
           },
           "sub_title": {
              "type": "string",
              "analyzer": "hebrew"
           },
           "tags": {
              "type": "string",
              "index": "not_analyzed"
           },
           "title": {
              "type": "string",
              "analyzer": "hebrew"
           },
           "type": {
              "type": "string",
              "index": "not_analyzed"
           },
           "waiting_talkbacks_counter": {
              "type": "integer"
           }
        }
     }
  }

} }

一些示例文档是：

好的，我的问题已经解决了。链接查询没有问题。我没有使用＆＃34; match_phrase_prefix＆＃34;正确的方法是，只有当你使用多个单词时才会使用单个单词，对于单个单词而言，正确的查询是为了自动完成搜索的形式（包含单词的一部分和不是一个完整的词）是 - ＆＃34;前缀＆＃34;。当链接这两者的任何组合并正确使用时 - 根本没有问题。

希望这可以帮助其他有类似问题的人。
