Hello,

I have the following data set.

```auto
POST /my_store/products/_bulk
{ "index": { "_id": 1 }}
{ "price" : 10, "productID" : "XHDK-A-1293-#fJ3" }
{ "index": { "_id": 2 }}
{ "price" : 20, "productID" : "KDKE-B-9947-#kL5" }
{ "index": { "_id": 3 }}
{ "price" : 30, "productID" : "JODL-X-1937-#pV7" }
{ "index": { "_id": 4 }}
{ "price" : 30, "productID" : "QQPX-R-3956-#aD8" }

```

What is the difference between the two queries below as both of them returns the same result.

```auto
GET /my_store/products/_search
{
  "query":{
          "bool":{
            "should":[
                {"term":{"price":20}},
                {"term":{ "productID" : "XHDK-A-1293-#fJ3"}}
              ],
            "must_not":{
                "term" : {"price" : 30}
              }
          }
        }
}

GET /my_store/products/_search
{
  "query":{
    "constant_score": {
        "filter": {
          "bool":{
            "should":[
                {"term":{"price":20}},
                {"term":{ "productID" : "XHDK-A-1293-#fJ3"}}
              ],
            "must_not":{
                "term" : {"price" : 30}
              }
          }
        }
    }
  }
}

```

Thanks.

I edited your post.

Most likely you should the difference in the output of those queries. One will have different values for `_score` and the other one has probably a `_score` of `1`.

Thanks for the reply. I am very newbie in Elastic Stack. Would be great if you could help in understanding how does this actually matters. In any of the scenario I am getting 3 records.

I think it does not really matter but queries without score computation should be faster.
