# Boolean operators

You can combine the filtering operators using Boolean operators. Combining Boolean operators results in a logical binary tree of possibilities. Because the binary tree is not easy to read, the `ViewConfig` provides a way of specifying a `Named Logical Array`.

      values:
      - "New"
      - "In Review"
```

{% hint style="info" %}
Filtering elements bundled together in a named array, are logically combined using the name of the array: either `AND` or `OR`. You can also nest these logical arrays, allowing all possible Boolean combinations.
