elasticsearch - Elasticsearch默认分析器无法分析

Question

我正在尝试为以下类型的索引定义默认分析器:

curl -X PUT "http://localhost:9200/index" -d '{
"index" : { 
    "analysis" : { 
        "filter": {
            "english_stop": {
              "type":       "stop",
              "stopwords":  "_english_"
            },  
            "english_stemmer": {
              "type":       "stemmer",
              "language":   "english" 
            },  
            "english_possessive_stemmer": {
              "type":       "stemmer",
              "language":   "possessive_english" 
            }   
        },  
        "analyzer" : { 
            "default" : { 
                "tokenizer" : "standard",
                "filter": [
                    "standard",
                    "english_possessive_stemmer",
                    "lowercase",
                    "english_stop",
                    "english_stemmer"
                ]   
            }   
        }   
    }   
}   
}'

但是，当搜索这些类型时，似乎未对文档进行分析，因为字段中的值未小写，未词干且不删除停用词。难道我做错了什么？我正在尝试分析文档而不定义文档结构。这个 page使我相信，设置默认的分析器索引应该可以分析我插入到 index/_type中的文档。

更新:

curl -X PUT "http://localhost:26319/index" -d '{
"settings" : { 
    "analysis" : { 
        "filter": {
            "english_stop": {
              "type":       "stop",
              "stopwords":  "_english_"
            },  
            "english_stemmer": {
              "type":       "stemmer",
              "language":   "english" 
            },  
            "english_possessive_stemmer": {
              "type":       "stemmer",
              "language":   "possessive_english" 
            }   
        },  
        "analyzer" : { 
            "default" : { 
                "tokenizer" : "standard",
                "filter": [
                    "standard",
                    "english_possessive_stemmer",
                    "lowercase",
                    "english_stop",
                    "english_stemmer"
                ]   
            }   
        }   
    }   
}   
}'

这是我正在运行的搜索:

curl -X GET "http://localhost:9200/index/_type/_search?q=penn+state+jersey&pretty"

这是映射:

{
  "index" : {
    "mappings" : {
  "_type" : {
    "properties" : {
      "description" : {
        "type" : "string"
      },
      "keyphrases_general" : {
        "type" : "string"
      },
      "keyphrases_specific" : {
        "type" : "string"
      },
      "name" : {
        "type" : "string"
      },
      "unique_id" : {
        "type" : "string"
      },
      "vendor" : {
        "type" : "string"
      }
    }
  }
    }
  }
}

这是一个文档示例:

{
  "_index" : "index",
  "_type" : "_type",
  "_id" : "518875234",
  "_score" : 1.1152786,
  "_source" : {
    "keyphrases_specific" : "Office Merchandise Tailgating Outdoor Clothing Man Cave",
    "name" : "Penn State Nittany Lions Classic Football Keychain - Licensed NCAA Gift - Penn State Nittany Lions Merchandise",
    "description" : "Check out this Penn State Nittany Lions Classic Football Keychain - Licensed NCAA Gift - Penn State Nittany Lions Merchandise. This product is perfect for a Penn State Nittany Lions fan. Show off your pride and add a great piece to your man cave! Made By Gamewear",
    "keyphrases_general" : "Sports Bedding Drinkware Licensed D�cor Accessories Gift",
    "vendor" : null,
    "unique_id" : null
  }
}

这也很奇怪，因为 penn state jersey和 penn state jerseys返回不同​​的搜索结果，尽管我认为由于 Jersey 不再是复数，所以它们应该返回相同的搜索结果。

您有一个小错字:JSON的第一层上index应该是settings

curl -X PUT "http://localhost:9200/index" -d '{
"settings" : {              <--- change this
    "analysis" : { 
        "filter": {

确保先删除您的索引，然后重试，这将起作用。
