In case you want to filter for a particular field you can use the method of `findBy` class. Unlike with the `find` method in this case you must set two parameters, the first is the field you want to filter and the second one the exact search value.
In case you want to find a particular instance you can use the class method `findOne`:
Contact.findBy "username", "@javi"
```
Contact.findOne since: 2014

> {username: "@javi", ...}

```
In case you want to find and modify a single instance you can use the class method `findAndModify`. This method recibes a document parameter with the embedded document fields.
+ **query**: *Optional*. The selection criteria for the modification. The query field employs the same query selectors as used in the `find` method. Although the query may match multiple documents, `findAndModify` will only select one document to modify.
+ **update**: Must specify either the update field. Performs an update of the selected document.
+ **upsert**: *Optional*. When `true`, `findAndModify` creates a new instance if no document matches the query or if documents match the query.
```
