ElasticSearch 7.6 multi-sub-document filtering query

Enterprise 2023-04-08 23:01:48 views: null

1. Field and official document address of es 7.x parent-child document

I searched for a long time, and it turns out that there are official tutorials, but the proper nouns are useless, so when I was looking for official documents, I kept lingering, let alone, and went to write the code first. I will continue to write later when I have time.

The es keyword explains the fields
supported by es 7.x in detail .

es 7.x parent-child document Join ,
es 7.x search request API
es 7.6 Java High Level REST Client API
es various Clients

The following examples are all based on es 7.6.0, and docker installation is convenient and fast. Remember to install kibana

2. Parent-child document structure design

  1. It should be noted here that it is best to define some specific attributes when creating a document, such as the date type, what type can be received, boolean, array, object, etc.
    insert image description here

1. General structure

PUT kikuu_test_product

{
    "settings": {
        "number_of_shards": 2,
        "number_of_replicas": 0,
        "refresh_interval": "50s"
    },
    "mappings": {
        "properties": {
            "productType": { 
            "type": "join",
                "relations": {
                    "product": [
                    "promotionActivityProduct",
                    "store"
                    ]
                }
            },
            "productStatus": {
                "type": "integer"
            },
            "productName": {
                "type": "keyword"
            },
           "productPrice": {
                "type": "keyword"
            },
           "productLowestPrice": {
                "type": "double"
            },
            "storeId": {
                "type": "keyword"
            },
            "storeStatus":{
                "type":"integer"
            },
            "startDate":{
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss || yyyy-MM-dd || epoch_millis"
            },
            "endDate":{
                "type": "date",
                "format": "yyyy-MM-dd HH:mm:ss || yyyy-MM-dd || epoch_millis"
            }
        }
    }
}

//如果后面还想再加数据的 field
PUT kikuu_test_product/_mapping
{
  "properties":{
    "startDate":{
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss || yyyy-MM-dd || epoch_millis"
    },
    "endDate":{
        "type": "date",
        "format": "yyyy-MM-dd HH:mm:ss || yyyy-MM-dd || epoch_millis"
    }
  }
}

2. Insert test data

If a new field is added on the basis of the original structure, then es will automatically recognize it, and it is very likely that the type of field recognized is keyword

Therefore, when designing the es data structure, it is best to define some important structures to prevent es from being automatically recognized as keywords later

① Parent document data

The following is the test data, request Rest

PUT kikuu_test_product/_doc/1?refresh
{
    "productType": {
        "name":"product"
    },
    "productName":"skirt",
    "productPrice":"221.005",
    "storeNumber":14384,
    "storeId":1,
    "productStatus":3
}

Execute the request 100 times and need to change some content each time. I directly use the data in the database to fetch the table and execute the conversion from excel to json on the website and then execute it with code.
If you are lazy, please provide it to me.
High Level Rest Client needs to be configured in advance

@Data
@Document(indexName = "kikuu_test_product", shards=2, refreshInterval="-1")

        JsonElement elements = jsonObject.get("list");

            elasticsearchClient.index(request, RequestOptions.DEFAULT);
        }
    }

② promotionActivityProduct data

This is not given the data, this is the data I changed myself.

  1. An average of about 5-6 is enough, and it is best to have an intersection with the following (that is, the parent document points to the same one)
  2. routing and parent need to point to the same parent document id
  3. One product corresponds to one active product
PUT /kikuu_test_product/_doc/a1?routing=22&refresh
{
    "productType": {
        "name":"promotionActivityProduct",
        "parent":"22"
    },
	"activityId": "1212420",
	"startDate": "2021-06-04 00:00:00",
	"endDate": "2021-06-30 00:00:00",
	"ActivityName": "Hot sale"
}

③ Insert sub-document store data

  1. One product corresponds to one store
  2. An average of about 5-6 is enough, it is best to have a cross with the above
  3. When storeStatus status == 20, the store is in normal business status.
PUT /kikuu_test_product/_doc/s6?routing=19&refresh
{
    "productType": {
        "name":"store",
        "parent":"19"
    },
    "storeId":"4",
    "storeStatus":20,
    "storeName":"Bebamour"
}

The official documentation is still awesome and well written.

Summary : All query conditions that can be implemented with requests can be implemented with code.

2. other Client。

For other versions, please refer to the official documents, there are detailed introductions, so I won’t go into details here.
