Elastic - Only return fully matching documents

Question

Having the following dataset:

[
{
 "id": 234,
 "category": "shoe"
},
{
 "id": 44,
 "category": "shoes"
},
{
 "id": 49,
 "category": "blue shoes"
},
{
 "id": 48,
 "category": "small shoes with glare"
}
]

Category's mapping is set to text.

And making a query like:

$query = (new ElasticQuery())
            ->setQuery([
                "bool" => [
                    "must" => [
                        "match" => [
                            "category" => [
                                "query" => "shoe size 22"
                            ],
                        ]
                    ]
                ],
            ]);

Elastic always returns me as first results/highest score:

• small shoes with glare
• blue shoes
• shoes

Rather than shoe.

How can i tell elastic that i only want documents whose match is 100% of category's content? (not query)

I mean, if my search doesn't contain "blue shoes", i don't want blue result to appear. I only expected to get shoe or shoe and shoes at max.

I can't use term, because as i said, i don't expect a full match with the query. I expect the matched documents field to be fully matched.

Examples:

• Query: shoe size 22
• Expected results:
• shoe

• Query: small shoes with glare
• Expected results:
• small shoes with glare
• shoes

• Query: blue shoes
• Expected results:
• blue shoes
• shoes

• Query: green shoes
• Expected results:
• shoes

As far as I know, there is no direct way to achieve your use case. You can use Percolate query to achieve your use case.

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

Index Mapping:

{
  "mappings": {
    "properties": {
      "category": {
        "type": "text"
      },
      "query": {
        "type": "percolator"
      }
    }
  }
}

Index Data:

{
  "query": {
    "match": {
      "category": {
        "query": "shoe"
      }
    }
  }
}
{
  "query": {
    "match": {
      "category": {
        "query": "shoes"
      }
    }
  }
}
{
  "query": {
    "match": {
      "category": {
        "query": "blue shoes",
        "operator": "AND"
      }
    }
  }
}
{
  "query": {
    "match": {
      "category": {
        "query": "small shoes with glare
",
        "operator": "AND"
      }
    }
  }
}

Search Query:

    {
      "query": {
        "percolate": {
          "field": "query",
          "document": {
            "category": "green shoes"
          }
        }
      }
    }

Search Result:

"hits": [
      {
        "_index": "65787899",
        "_type": "_doc",
        "_id": "2",
        "_score": 0.13076457,
        "_source": {
          "query": {
            "match": {
              "category": {
                "query": "shoes",
                "operator": "AND"
              }
            }
          }
        },
        "fields": {
          "_percolator_document_slot": [
            0
          ]
        }
      }
    ]
