# Complex queries

Use the "where" argument to construct complex queries that has multiple conditions and nesting levels. For e.g. to query all car assets manufactured after year 2010:

<pre class="language-graphql"><code class="lang-graphql"><strong>query {
</strong>    car (where: {year: {_gt: 2010} }) {
        Id
        make
        color
    }
}
</code></pre>

Response:

<pre class="language-json"><code class="lang-json"><strong>{
</strong>    "data": {
        "car_count": 1,
        "car": [
            {
                "Id": "car1",
                "color": "red",
                "make": "ford"
            }
        ]
    }
}
</code></pre>

The query can include multiple conditions and include conditions on nested object fields too. For a complete list of supported operators, refer to [Operator](https://docs.spydra.app/developers/api-reference/asset-tokenization/graphql/operators)

```graphql
query {
    car (where: {
        _and: [
                {year: {_gt: 2010} },
                {engine: {isDefective: {_eq: true}}}
              ]
            }
        ) {
        Id
        make
        color
    }
}
```

Response:

```json
{
    "data": {
        "car_count": 1,
        "car": [
            {
                "Id": "car1",
                "color": "red",
                "make": "ford"
            }
        ]
    }
}
```
