elasticsearch 弹性术语查询的意外结果

我有弹性2.4只运行测试

安装程序 作为一个全新的开始，我在索引中创建了1个项目，而且只有1个项目

$ curl -s -XPUT "http://localhost:9200/movies/movie/1" -d'
{
    "title": "The Godfather",
    "director": "Francis Ford Coppola",
    "year": 1972,
    "genres": ["Crime", "Drama"]
}'

返回

{"_index":"movies","_type":"movie","_id":"1","_version":3,"_shards":{"total":2,"successful":1,"failed":0},"created":false}

{"took":8,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":0.095891505,"hits":[{"_index":"movies","_type":"movie","_id":"1","_score":0.095891505,"_source":
{
    "title": "The Godfather",
    "director": "Francis Ford Coppola",
    "year": 1972,
    "genres": ["Crime", "Drama"]
}}]}}

然后，我运行此命令以确认索引正常工作：

$ curl -s -XPOST "http://localhost:9200/movies/_search" -d'
{
    "query": {
        "query_string": {
            "query": "Godfather"
        }
    }
}'

返回

{"_index":"movies","_type":"movie","_id":"1","_version":3,"_shards":{"total":2,"successful":1,"failed":0},"created":false}

{"took":8,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":1,"max_score":0.095891505,"hits":[{"_index":"movies","_type":"movie","_id":"1","_score":0.095891505,"_source":
{
    "title": "The Godfather",
    "director": "Francis Ford Coppola",
    "year": 1972,
    "genres": ["Crime", "Drama"]
}}]}}

问题 我尝试像这样运行术语查询：

$ curl -s -XPOST "http://localhost:9200/movies/_search" -d'
{
    "query": {
        "term": {"title": "The Godfather"}
    }
}'

$ curl -s -XPUT "http://localhost:9200/movies/_mapping/movie" -d'
{
    "properties": {
        "title": {
            "type": "string",
            "fields": {
               "raw": {
                   "type": "string",
                   "index": "not_analyzed"
               }
            }
        }
    }
}'

我本应得到1个结果，但我得到了以下结果：

{"took":1,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}

我做错了什么？

要么像jay建议的那样匹配短语，要么你需要创建一个

未分析的子字段（例如
title.raw
），如下所示：

$ curl -s -XPOST "http://localhost:9200/movies/_search" -d'
{
    "query": {
        "term": {"title": "The Godfather"}
    }
}'

$ curl -s -XPUT "http://localhost:9200/movies/_mapping/movie" -d'
{
    "properties": {
        "title": {
            "type": "string",
            "fields": {
               "raw": {
                   "type": "string",
                   "index": "not_analyzed"
               }
            }
        }
    }
}'

然后，您可以重新索引文档以填充
标题。原始
：

$ curl -s -XPUT "http://localhost:9200/movies/movie/1" -d'
{
    "title": "The Godfather",
    "director": "Francis Ford Coppola",
    "year": 1972,
    "genres": ["Crime", "Drama"]
}'

最后，您的术语查询将在
title.raw
子字段中工作：

$ curl -s -XPOST "http://localhost:9200/movies/_search" -d'
{
    "query": {
        "term": {"title.raw": "The Godfather"}
    }
}'

“教父”
，因此
匹配
似乎不适合我的需要。我是否可以使用给定的数据进行术语查询？请尝试使用匹配短语。已分析
