# RegExIsMatch

{% hint style="info" %}
The **`RegExIsMatch()`** function checks a <mark style="color:blue;">text</mark> for a pattern if it can be found. &#x20;

All regex functions use a pattern to check for matches in the input text.&#x20;

For a more complete explanation and special / allowed characters you can visit [**this WEM Forum post**](https://my.wem.io/forum?threadid=459). Here you find a cheat-sheet and a few helpful examples.&#x20;

This function is NOT SQL compatible. For more information about SQL compatibility, see our [documentation](/platform/wemreference/sql-compatibility.md).
{% endhint %}

{% hint style="success" %}
Returns <mark style="color:green;">True</mark> if the pattern is found in <mark style="color:blue;">text</mark>.

Returns <mark style="color:red;">False</mark> if the pattern is not found in <mark style="color:blue;">text</mark>.&#x20;

Returns <mark style="color:red;">\[unknown]</mark> if no matches are found or the pattern is faulty.
{% endhint %}
