Sort is incorrect

Elastic Stack Elasticsearch
1

My mapping:

{
  "my_index": {
    "mappings": {
      "properties": {
        "attributesRecommend": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "attributesSearch": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "price": {
          "type": "double"
        }
      }
    }
  }
}

My query to ES:

{"query":{"bool":{"must":[{"terms":{"status":["publish","sold","sold_by_merchant"]}},{"match":{"type":"sale"}}],"should":[{"multi_match":{"query":"*Toyota*","type":"phrase_prefix","fields":["textSearch","attributesSearch"]}},{"match":{"textSearch":{"query":"*Toyota*"}}},{"match":{"attributesSearch":{"query":"*Toyota*"}}}]}},"from":0,"size":20,"sort":["_score",{"price":{"order":"asc"}}]}

Sort with "price" is incorrect.
I checked in my result hits

{
...
 "sort": [15.456814, 34000]
}

When I remove "_score" from the sort, the keyword query is no longer correct

I want search match and sort correctly with the above condition.
How can I resolve it? Or have any solutions?
Thanks

Welcome!

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script is something anyone can copy and paste in Kibana dev console, click on the run button to reproduce your use case. It will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.

Have a look at the Elastic Stack and Solutions Help · Forums and Slack | Elastic page. It contains also lot of useful information on how to ask for help.

What happens if you change the order or the sort criteria and sort on price first and score second?

If this does not help you need to provide a few sample documents that help show the issue so we can recreate it (which is what David was asking for). You also need to explain the result you are expecting and what you are actually seeing.

It is also always recommended to tell which version of Elasticsearch you are using as behavioir can change over time.

Hi,
My query

{
  "query": {
    "bool": {
      "must": [
        { "terms": { "status": ["publish", "sold", "sold_by_merchant"] } },
        { "match": { "type": "sale" } },
        { "match": { "manufactureYear": 2021 } },
        {
          "bool": {
            "should": [
              {
                "multi_match": {
                  "query": "*toyota Avensis 2021*",
                  "type": "phrase_prefix",
                  "fields": ["textSearch", "attributesSearch"]
                }
              },
              {
                "match": { "textSearch": { "query": "*toyota Avensis 2021*" } }
              },
              {
                "match": {
                  "attributesSearch": { "query": "*toyota Avensis 2021*" }
                }
              }
            ]
          }
        }
      ]
    }
  },
  "from": 0,
  "size": 5,
  "sort": ["_score", {"price":{"order":"desc"}}]
}

and here my result hits:

      {
        "_index": "my_index",
        "_id": "7830",
        "_score": 5.859531,

        },
        "sort": [5.859531, 555]
      }
    ]
  }
}

My expected result is sort by price from low to high.
I tried leaving "_score" out of my query. Sort by price is correct but results by keyword are no longer correct.
Elasticsearch v8.7.0
Looking forward to hearing from everyone soon.

Did you try what I suggested? If so, what was the result?

11

If I change the order with your suggest:

{"query":{"bool":{"must":[{"terms":{"status":["publish","sold","sold_by_merchant"]}},{"match":{"type":"sale"}}],"should":[{"multi_match":{"query":"*Toyota Alphard*","type":"phrase_prefix","fields":["textSearch","attributesSearch"]}},{"match":{"textSearch":{"query":"*Toyota Alphard*"}}},{"match":{"attributesSearch":{"query":"*Toyota Alphard*"}}}]}},"from":0,"size":20,"sort":[{"price":{"order":"asc"}},"_score"]}

Result with query above:

{
  "took": 5,
  "timed_out": false,
  "_shards": { "total": 1, "successful": 1, "skipped": 0, "failed": 0 },
  "hits": {
    "total": { "value": 3009, "relation": "eq" },
    "max_score": null,
    "hits": [
      {
        "_index": "lb_carz",
        "_id": "6456",
        "_score": 1.177574,
        "_source": {
          "id": 6456,
          "textSearch": "ChevroletKMCamaroChevroletCamaro雪佛兰ZH科迈罗 Chevrolet KM Camaro Chevrolet Camaro 雪佛兰 ZH 科迈罗",
          "price": -1,
          "attributesSearch": "ថ្មី New 新"
        },
        "sort": [-1, 1.177574]
      },
      {
        "_index": "lb_carz",
        "_id": "3663",
        "_score": 1.177574,
        "_source": {

        },
        "sort": [0, 1.177574]
      },
      {
        "_index": "lb_carz",
        "_id": "3667",
        "_score": 1.177574,
        "_source": {

          "textSearch": "BMWi8BMWi8宝马i8 BMW i8 BMW i8 宝马 i8",
          "price": 0,
          "attributesSearch": "ថ្មី New 新"
        },
        "sort": [0, 1.177574]
      },
      {
        "_index": "lb_carz",
        "_id": "3719",
        "_score": 1.177574,
        "_source": {
          "id": 3719,
          "textSearch": "BMWi8BMWi8宝马i8 BMW i8 BMW i8 宝马 i8",
          "price": 0,
          "attributesSearch": "ថ្មី New 新"
        },
        "sort": [0, 1.177574]
      },
      {
        "_index": "lb_carz",
        "_id": "3720",
        "_score": 1.177574,
        "_source": {
          "id": 3720,
          "textSearch": "BMWi3SeriesBMWi3Series宝马i3系 BMW i3 Series BMW i3 Series 宝马 i3 系",
          "price": 0,
          "attributesSearch": "ថ្មី New 新"
        },
        "sort": [0, 1.177574]
      }
    ]
  }
}

The results seem to have nothing to do with the keyword. The query retrieves the smallest price in my dataset and sort

Can you set the minimum_should_match parameter to 1 for the should block? There is an example in the docs I linked to. Keep the sorting order used in the last query.
