Querying with boolean logic¶

Adding query clauses to the must key¶

GET /recipe/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        },
        {
          "range": {
            "preparation_time_minutes": {
              "lte": 15
            }
          }
        }
      ]
    }
  }
}

Moving the range query to the filter key¶

GET /recipe/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        }
      ],
      "filter": [
        {
          "range": {
            "preparation_time_minutes": {
              "lte": 15
            }
          }
        }
      ]
    }
  }
}

Adding a query clause to the must_not key¶

GET /recipe/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "ingredients.name": "tuna"
          }
        }
      ],
      "filter": [
        {
          "range": {
            "preparation_time_minutes": {
              "lte": 15
            }
          }
        }
      ]
    }
  }
}

Adding a query clause to the should key¶

GET /recipe/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        }
      ],
      "must_not": [
        {
          "match": {
            "ingredients.name": "tuna"
          }
        }
      ],
      "should": [
        {
          "match": {
            "ingredients.name": "parsley"
          }
        }
      ],
      "filter": [
        {
          "range": {
            "preparation_time_minutes": {
              "lte": 15
            }
          }
        }
      ]
    }
  }
}

The behavior of should query clauses depends¶

GET /recipe/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
            "ingredients.name": "pasta"
          }
        }
      ],
      "should": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        }
      ]
    }
  }
}

GET /recipe/_search
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "ingredients.name": "parmesan"
          }
        }
      ]
    }
  }
}
