问在Elasticsearch中如何在查询时而不是索引时间使用同义词

/* NOTE: This was all run against elasticsearch 1.5 (if that matters; documentation is identical in 2.x) */

// Create our synonyms filter and analyzer on the index
PUT my_synonyms_test
{
  "settings": {
    "analysis": {
      "filter": {
        "my_synonym_filter": {
          "type": "synonym",
          "synonyms": [
            "queen,monarch"

        }

      "analyzer": {
        "my_synonyms": {
          "tokenizer": "standard",
          "filter": [
            "lowercase",
            "my_synonym_filter"
          ]
        }
      }
    }
  }
}

// Create a mapping that uses this analyzer
PUT my_synonyms_test/rulers/_mapping
{
  "properties": {
    "name": {
      "type": "string"
    },
    "title": {
      "type": "string",
      "analyzer": "my_synonyms"
    }
  }
}

// Some data
PUT my_synonyms_test/rulers/1
{
  "name": "Elizabeth II",
  "title": "Queen"
}

// A query which utilises the synonyms
GET my_synonyms_test/rulers/_search
{
  "query": {
    "match": {
      "title": "monarch"
    }
  }
}

// And we get our expected result back:
