ElasticSearch : IN equivalent operator in ElasticSearch

Question

I am trying to find ElasticSearch query equivalent to IN \\ NOT in SQL.

I know we can use QueryString query with multiple OR to get the sam

Answer 1

1 terms

you can use terms term query in ElasticSearch that will act as IN

terms query is used to check if the value matches any of the provided values from Array.

2 must_not

must_not can be used as NOT in ElasticSearch.

ex.

GET my_index/my_type/_search
{
    "query" : {
         "bool" : {
              "must":[
                {
                   "terms": {
                        "id" : ["1234","12345","123456"]
                    }
                },
                {
                   "bool" : {
                        "must_not" : [
                            {
                              "match":{
                                  "id" : "123"
                               }
                            }
                        ]
                    }
                }
              ]
         }
    }
}

3. exists

Also if it helps you can also use "exists" query to check if the field exists or not. for ex, check if the field exists

"exists" : {
      "field" : "mobileNumber"
   }

check if a field does not exist

"bool":{
    "must_not" : [
        {
           "exists" : {
               "field" : "mobileNumber"
           }
        }
     ]
}
