My first question in the group:
Where is the search function in the Forum?
(why ask something that IS solved)
Welcome to the forum.
It is in the upper right corner as seen in the attached picture.
That's a hoot. I never noticed that search window in the upper right corner.
I've always used the one that is in the header bar between "Home" and "Members (first photo), which brings up the more detailed options window (second photo).
And cleverly enough, if you don't enter anything in the input box next to the search button at the top, it will graciously redirect you to the same options window.
So when I search for words only, I use it, and also if I need to add a few options.
Also, when you're in a given topic/board, the dropdown next to the top search button will default to "this topic"/"this board" so you will only get hits inside the current context. But you can still revert it to "Entire forum".
