title: Operators
---
Liquid includes many logical and comparison operators.
## Basic operators
<table>
<tbody>
<tr>
<td><code>==</code></td>
<td>equals</td>
</tr>
<tr>
<td><code>!=</code></td>
<td>does not equal</td>
</tr>
<tr>
<td><code>&gt;</code></td>
<td>greater than</td>
</tr>
<tr>
<td><code>&lt;</code></td>
<td>less than</td>
</tr>
<tr>
<td><code>&gt;=</code></td>
<td>greater than or equal to</td>
</tr>
<tr>
<td><code>&lt;=</code></td>
<td>less than or equal to</td>
</tr>
<tr>
<td><code>or</code></td>
<td>logical or</td>
</tr>
<tr>
<td><code>and</code></td>
<td>logical and</td>
</tr>
</tbody>
</table>
For example:
```liquid
{% raw %}
{% if product.title == "Awesome Shoes" %}
These shoes are awesome!
{% endif %}
{% endraw %}
```
You can use multiple operators in a tag:
```liquid
{% raw %}
{% if product.type == "Shirt" or product.type == "Shoes" %}
This is a shirt or a pair of shoes.
{% endif %}
{% endraw %}
```
## contains
`contains` checks for the presence of a substring inside a string.
```liquid
{% raw %}
{% if product.title contains 'Pack' %}
This product's title contains the word Pack.
{% endif %}
{% endraw %}
```
`contains` can also check for the presence of a string in an array of strings.
```liquid
{% raw %}
{% if product.tags contains 'Hello' %}
This product has been tagged with 'Hello'.
{% endif %}
{% endraw %}
```
`contains` can only search strings. You cannot use it to check for an object in an array of objects.
