Does zotero advanced search (pdf content) support regex ?

I want to search items such as “item1.{1,17}item2”.

This phrase can help me find certain sentences contained item1 and item2

When searching for "Attachment content" in advanced search, you can select regex using the small arrow/triangle on the left of the search field.

Ah you are right, but the triangle is very hard to see (note that it is only visible when selecting "Attachment Content"). Here's a screenshot to show where exactly the triangle is: https://imgur.com/a/ngHlWSr
