弹性搜索多字搜索不起作用

Question

我正在尝试对连续类型的字段进行搜索查询。我也配置了同义词。我没有得到搜索查询的任何结果。

synonyms.txt的内容

iit, indian institute of technology
iitg, indian institute of technology guwahati

创建指数机构：

curl -XDELETE 'http://localhost:9200/institutes/'

curl -XPUT 'http://localhost:9200/institutes/' -d '{
  "settings": {
    "index": {
      "analysis": {
        "analyzer": {
          "suggest_synonyms": {
            "type": "custom",
            "tokenizer": "whitespace",
            "filter": ["lowercase","my_synonyms"]
          }
        },
        "filter" : {
          "my_synonyms" : {
              "type" : "synonym",
              "synonyms_path" : "synonyms.txt"
          }
        }
      }
    }
  },
  "mappings": {
    "institute" : {
      "properties" : {
        "name" : { "type" : "string","index": "not_analyzed" },
        "name_suggest" : {
          "type" :            "completion",
          "index_analyzer" :  "suggest_synonyms",
          "search_analyzer" : "suggest_synonyms",
          "preserve_position_increments": false,
          "preserve_separators": false
        }
      }
    }
  }
}'

参赛作品：

curl -X PUT 'localhost:9200/institutes/institute/3?refresh=true' -d '
{
  "name" :         "iitg",
  "name_suggest" : "iitg"
}'

curl -X PUT 'localhost:9200/institutes/institute/2?refresh=true' -d '
{
  "name" :         "indian institute of technology guwahati",
  "name_suggest" : "indian institute of technology guwahati"
}'

curl -X PUT 'localhost:9200/institutes/institute/1?refresh=true' -d '
{
  "name" :         "indian institute of technology",
  "name_suggest" : "indian institute of technology"
}'

不起作用的查询：

curl -X POST 'localhost:9200/institutes/_search?pretty' -d '
{
    "query" : {
        "filtered" : {
            "filter" : {
                "terms" : {
                    "name_suggest" : ["iit"]
                }
            }
        }
    }
}'

curl -X POST 'localhost:9200/institutes/_search?pretty' -d '
{
    "query": {
        "match": {
            "name_suggest": "iitg"
        }
    }
}'


curl -X POST 'localhost:9200/institutes/_search?pretty' -d '
{
    "query": {
        "match": {
            "name_suggest": "indian institute of technology"
        }
    }
}'

我正在对name_suggest进行查询。在我的生产数据库中我没有列name_suggest这是我正在测试和尝试的东西。

上面的所有三个查询都没有返回任何结果。请告诉我这里做错了什么。

更新：添加了_analyze的输出

curl -XGET＆＃39; localhost：9200 / institutes / _analyze？analyzer = suggest_synonyms＆amp; pretty = 1＆＃39; -d＆＃39; 印度理工学院guwahati ＆＃39;

{
  "tokens" : [ {
    "token" : "iit-g",
    "start_offset" : 1,
    "end_offset" : 40,
    "type" : "SYNONYM",
    "position" : 1
  }, {
    "token" : "iitg",
    "start_offset" : 1,
    "end_offset" : 40,
    "type" : "SYNONYM",
    "position" : 1
  }, {
    "token" : "indian",
    "start_offset" : 1,
    "end_offset" : 7,
    "type" : "SYNONYM",
    "position" : 1
  }, {
    "token" : "institute",
    "start_offset" : 8,
    "end_offset" : 17,
    "type" : "SYNONYM",
    "position" : 2
  }, {
    "token" : "of",
    "start_offset" : 18,
    "end_offset" : 20,
    "type" : "SYNONYM",
    "position" : 3
  }, {
    "token" : "technology",
    "start_offset" : 21,
    "end_offset" : 31,
    "type" : "SYNONYM",
    "position" : 4
  }, {
    "token" : "guwahati",
    "start_offset" : 32,
    "end_offset" : 40,
    "type" : "SYNONYM",
    "position" : 5
  } ]
}
