### Binary operators in `where_exp` filter {%- include docs_version_badge.html version="4.0" -%}
You can use Liquid binary operators `or` and `and` in the expression passed to the `where_exp` filter to employ multiple
conditionals in the operation.
For example, to get a list of documents on English horror flicks, one could use the following snippet:
```liquid
{% raw %}{{ site.movies | where_exp: "item", "item.genre == 'horror' and item.language == 'English'" }}{% endraw %}
```
Or to get a list of comic-book based movies, one may use the following:
```liquid
{% raw %}{{ site.movies | where_exp: "item", "item.sub_genre == 'MCU' or item.sub_genre == 'DCEU'" }}{% endraw %}
```
