        <pre>Description:
<a href="https://help.libreoffice.org/Common/List_of_Regular_Expressions">https://help.libreoffice.org/Common/List_of_Regular_Expressions</a> doesn't say
anything about regexp lookaround patterns (see
<a href="https://www.regular-expressions.info/lookaround.html">https://www.regular-expressions.info/lookaround.html</a>).

Steps to Reproduce:
I'd love to add this information but <a href="https://help.libreoffice.org/Main_Page">https://help.libreoffice.org/Main_Page</a>
says there's no way to participate.

Actual Results:  
Lookaround patterns do in fact work

Expected Results:
=SEARCH("(?<=a)b", "cab")  // 3


Reproducible: Always


User Profile Reset: No
