无法匹配包含查询中指定的所有单词的文档

Question

I am struggling to get only those documents which contains word1 and word2 both at least. I tried multiple ways to form request but still fails to fetch required records. Below request returns document even if word1 is missing from document but it contains word2 .

{
    "query": {
        "bool": {
            "filter": [
                {
                    "term": {
                        "source": "source1"
                    }
                },
                {
                    "term": {
                        "qty": "1"
                    }
                }
            ],
            "must": [
                {
                    "match": {
                        "product_name": {
                            "query": "word1 word2",
                            "fuzziness": "AUTO"
                        }
                    }
                }
            ]
        }
    }
}

Answer 1

Tldr;

There are many ways to achieve this. Either with a terms query for keywords type fields or query_string for text fields.

Solution

Assuming the field product_name is of type text.

POST /_bulk
{"index":{"_index":"74018346"}}
{"product_name":"This sentence has word1 and word2"}
{"index":{"_index":"74018346"}}
{"product_name":"this sentence only has word1"}
{"index":{"_index":"74018346"}}
{"product_name":"in this one, only word2 is present"}
{"index":{"_index":"74018346"}}
{"product_name":"None of the words are presents"}


GET 74018346/_search
{
  "query": {
    "query_string": {
      "query": "word1 AND word2",
      "default_field": "product_name"
    }
  }
}
