一个简单的AND查询与弹性搜索 [英] A simple AND query with Elasticsearch

问题描述

我正在为两个指定的字段做一个简单的查询，手册和谷歌被证明是没有什么帮助的。下面的例子应该很清楚我想做什么。

I am trying to do a simple query for two specified fields, and the manual and google is proving to be of little help. Example below should make it pretty clear what I want to do.

{
  "query": {
      "and": {
        "term": {
          "name.family_name": "daniel",
          "name.given_name": "tyrone"
        }
      }
   }
}

作为一个奖金问题，为什么找到丹尼尔Tyrone与丹尼尔，但不是如果我搜索丹尼尔。它的行为就像一个真实的奇怪的反区分大小写搜索。

As a bonus question, why does it find "Daniel Tyrone" with "daniel", but NOT if I search for "Daniel". It behaves like a realy weird anti case sensitive search.

推荐答案

编辑：更新，对不起。您需要在Bool查询内的每个字段单独的术语对象：

Updated, sorry. You need a separate Term object for each field, inside of a Bool query:

{
  "query": {
    "bool": {
        "must" : [
          {
           "term": {
             "name.family_name": "daniel"
           }
         },
         {
           "term": {
             "name.given_name": "tyrone"
           }
         }
       ]
     }
   }
}

ElasticSearch不会对术语查询进行分析，这使得它们区分大小写。一个术语查询表示ES在您的索引中查找这个确切的令牌，包括案例和标点符号。

Term queries are not analyzed by ElasticSearch, which makes them case sensitive. A Term query says to ES "look for this exact token inside your index, including case and punctuation".

如果你想要不区分大小写，您可以在分析器中添加关键字+小写过滤器。或者，您可以使用在查询时分析文本的查询（例如 Match 查询）

If you want case insensitivity, you could add a keyword + lowercase filter to your analyzer. Alternatively, you could use a query that analyzes your text at query time (like a Match query)

Edit2：您也可以使用And或Bool过滤器。

You could also use And or Bool filters too.
