Trouble trying to use Windows Search to search for file with a question mark in the content

It seems that Windows Search is having trouble when I specify a question mark character as the content that I'm searching for within my files.

I've tried:

• content:?
• content:"?"
• content:"\?"
• content:\?
• content:%3f
• content:"%3f"
• content:\3f
• content:"\3f"
• content:\00\00\00\3F

but each of these yield no results when I do indeed have files that contain ? within the scope of the search. If I instead search for something like content:happy it will indeed find all files with the phrase "happy" within those same files.

My assumption is that Windows Search is treating some characters such as the question mark as a special character likely for the purpose of wild card expressions. To test this theory I've also searched for files containing an asterisk * and indeed I have the same issue as when searching for content of question mark. What I'm wondering is whether there is any way to get a search to work where I can search for a literal expression without any type of wildcard matching or at least a way to escape the special characters within the expression.

By the way I'm using Windows 7 Enterprise.

Try ~=? where ? is the character you are searching for.

It looks like Microsoft has removed the ability to search just for special characters. In order to search with special characters there must also be a word included with it (Example: Who?). Again, there must be a word, not just a wildcard, with the special character. That is because Windows Search ignores the special characters with the exception of the wildcards?. Per this indows Search Tips and Tricks page, the only wildcards that available within Windows Search are asterisk and question mark. However, it seems that the only one that works is the asterisk. Even when trying its example, s?n, found on the same page page.

Actually, the problem is a little different. Search is now word-based, not character based. Brackets are considered punctuation by Search, not wild cards. To get meaningful results, queries that contain punctuation must also contain words, a phrase, or a wild card. For example, If I search on this:[*] or this: {*} I get a bunch of files that have a phrase in their file name within brackets, just as I would expect. So give that a try.
