弹性搜索结合短语和 substring 查询

Question

For input sentence:

quick brown fox

I need to get matching for quick brown (phrase match) but also to uic (regex match). How can this be achieved?

Answer 1

You can use a boolean query to combine match phrase and regexp query .

Adding a working example with index data, search query and search result

Index Data:

{
    "title":"quick brown fox"
}

Search Query:

{
  "query": {
    "bool": {
      "should": [
        {
          "match_phrase": {
            "title": "quick brown"
          }
        },
        {
          "regexp": {
            "title": {
              "value": ".*uic.*"
            }
          }
        }
      ]
    }
  }
}

Search Result:

"hits": [
      {
        "_index": "65777213",
        "_type": "_doc",
        "_id": "1",
        "_score": 1.5753641,
        "_source": {
          "title": "quick brown fox"
        }
      }
    ]
