Jonah, (the forum is not letting me reply in the same thread as your response, so I had to back up this one level)
sorry if I am appearing "anal" about this, I'm just trying to understand what it is that you have entered and where you entered it.
Just saying something like "it doesn't work" does not give me specifically what you tried, and where, as in what field, you entered it.
I know what I have mentioned does work because I have been using these syntaxes for years. I support many dozens of people here at a major corporation (call it company X - hint, hint) and I show those people how to use the tools, the PCs and software, at hand.
I have seen, sometimes, a person will tell me something like "oh I tried EXACTLY what you said, and I didn't get xxx to work."
And then I check what it is that they actually tried and I find that they left a "little" part out, or entered a quote when they shouldn't have or not entered a quote when they should have, or they just used the wrong character entirely.
So, if you can tell me what exactly you entered, and what window and what field you entered it, along with any other pertinent information, I am sure we can resolve this.
And like someone else said, in a parallel thread, sure there are better search tools, but I know that Windows Explorer Find/Search will do what it is you want to do.
Using another tool, some share or freeware, will bring its own syntax and particulars to the game, and you'd have to learn them as well.
