# Match all query
The most simple query, which matches all documents, giving them all a `_score` of `1.0`.
```json

{
    "query": {
        "match_all": {}
    }
}
```

The `_score` can be changed with the `boost` parameter:
```json

{
  "query": {
    "match_all": { "boost" : 1.2 }
  }
}
```


## Match None Query

This is the inverse of the `match_all` query, which matches no documents.
```json

{
  "query": {
    "match_none": {}
  }
}
```
