By default, Everything puts the * (asterisk) wildcard at the beginning and end of what you type when you enter a search, but if you explicitly include a wildcard it does NOT do this. So for example if I type in foobar it will find all files that contain foobar anywhere in the filename, but if I type in foobar* it will only find files that start with foobar.
Continuing with this example, I found it very strange when I typed in foobar and got a list of files, that this list would then get reduced to a shorter list when I added * at the end. I didn't come to understand the EXACT reason that this was happening until sometime later (via an AI query - I think this AI stuff is going to catch on!
I would suggest that an explanation of how this works appear in the top item of this pinned help topic, and added to the top of the "Help > Search Syntax" menu item.
