How to access Advanced Tag Search?


I’ve started to use Joplin some weeks ago at work to build an extensive personal knowledge base.

Unfortunately, I can’t figure out how to use the advanced search.

A Jolpin help note states:

To search for more sophisticated tag combinations, use the command Search for Tag Combination (Control + T) from the searchmenu.

What ist meant with searchmenu? The only search-related items in the menu are Edit/Search in all the notes and Edit/Search in the current note. And if I press Ctrl+T in search bar, I get a new note. What do I miss?
