Elasticsearch Notes

on Shenzhen

This notes will store some unstructured tips when I study Elasticsearch.

Exactly search in array

Generate docs and search “Tony Ma” in the tags:

PUT twitter/blog/1
{ "Company" : "Tencent",
  "tg" : ["Tony Ma", "Tencent"]
}

PUT twitter/blog/2
{ "Company" : "Alibaba",
  "tg": ["Tony", "Ma"]
}

GET twitter/blog/_search?q=tg:"Tony Ma"

Returns:

{
  "took": 1,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 1,
    "max_score": 0.5063205,
    "hits": [
      {
        "_index": "twitter",
        "_type": "blog",
        "_id": "1",
        "_score": 0.5063205,
        "_source": {
          "Company": "Tencent",
          "tg": [
            "Tony Ma",
            "Tencent"
          ]
        }
      }
    ]
  }
}

Remarks:

  1. The field names should be different in different types.
