“match” query along with “should” clause giving more than required match results in Elasticsearch

Question

I have written the following lucene query in elasticsearch for getting documents with Id field as mentioned:

GET requirements_v3/_search
  {
   \"from\": 0,          


        

Answer 1

As you said that your Id is text as well as keyword so you should use Id.keyword for matching exact values like

GET requirements_v3/_search
  {
   "from": 0, 
   "size": 10, 
   "query": {
   "bool": {
  "filter": {
    "bool": {
      "should": [
    {"match": {
      "Id.keyword": "b8bf49a4-960b-4fa8-8c5f-a3fce4b4d07b"
    }},
    {
      "match": {
      "Id.keyword": "048b7907-2b5a-438a-ace9-f1e1fd67ca69"
      }
    }
  ]
 }
 }
 }     
}

But I guess you should use terms if you wants to match multiple exact values. Have a look here. For an example:

{
    "terms" : {
        "Id" : ["b8bf49a4-960b-4fa8-8c5f-a3fce4b4d07b", "048b7907-2b5a-438a-ace9-f1e1fd67ca69"]
    }
}
