Team.findOne({ where: { city: 'windsor' }})
```
You can also do more complex queries by setting the value of a key to JSON.
```js
// returns only teams that have a `address.city` property of "windsor"
// GET /team?city={"address": "windsor"}
// or
// GET /team?city[address]=windsor
// results in the Sequelize query:
Team.findOne({ where: { address: { city: 'windsor' }}})
```
## `include` queries
Getting related models is easy, just use a query parameter `include`.
```js
// returns all teams with their related City model
// GET /teams?include=city
// GET /teams?include=city or
// GET /teams?include={"include": {"model": "City"}}}
// results in a Sequelize query:
Team.findAll({include: City})

// returns all team with their related City where City property name equals Healdsburg
// GET /teams?include={"include": {"model": "City", "where": {"name": "Healdsburg"}}}
// results in a Sequelize query:
Team.findAll({include: {model: City, where: {name: 'Healdsburg'}}})

## `limit` and `offset` queries
Restricting list (`GET`) and scope queries to a restricted count can be done by passing `limit=<number>` and/or `offset=<number>`.
