Sorry Motman, my description was not all that accurate, I will try again:-
Click on your name, that brings up a list of your posts.
On the right of the screen just above the first post listed is, 'Filter' , this brings up a box with 3 columns of options.
In the box at the bottom of the 3rd column, headed, 'Source', is, 'Advance' in blue text.
It looks as though the Advance search is about the same as it used to be.
You can use your Internet Browsers back/forward keys to jump between these notes and where you are working.
Browser back/forward keys are usually arrows on the upper left on the Browser frame.
Good Luck.
