I have these two queries

**First**

```
GET propertywebsites3/_search
{
  "_source": "city", 
  "query": {
    "bool": {
      "filter": {
        "term": {
          "city.raw": "Dubai"
        }
      }
    }
  }
}

```

**Seond**

```
GET propertywebsites3/_search
{
  "_source": "city", 
  "query": {
    "filtered": {
      "filter": {
        "term": {
          "city.raw": "Dubai"
        }
      }
    }
  }
}

```

The first one gives 0 for all the scores, I see that in this page [https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html) it is written that if you use the filter clause in a bool clause, all matching documents will have 0 in the score,

and the second query gives 1 to the score of all the documents.

first of all why not both of them either 0 or 1. second aren't they supposed to do they same? which is filtering all the documents that its city is "Dubai" ?

thanks

Filtered query has been deprecated. See [https://www.elastic.co/guide/en/elasticsearch/reference/2.2/query-dsl-filtered-query.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.2/query-dsl-filtered-query.html)

If you add a match\_all query in the must clause of the bool query, what is the score?

Thanks for your reply.

If I add a match\_all, the score becomes all 1 instead of 0.

So if I understood you correctly, whenever i want to do a filter now, I should use a bool clause with a filter clause inside , right please?

right!

So the reason with the difference between the score is that the `filtered` query actually adds a `match_all` query which set the `_score` to 1 for each document and the `bool` query does not add a query.
