long established preferences for allowing WILDCARDS in search strings?
The Outlook help file (if you search it for "search criteria") will most likely show you something like this:
Use complex search criteria to find files
When you click Files in the Look for box (on the Advanced Find dialog box) to search for files on your computer or a network, you can use complex search criteria in the Named and Search for the word(s) boxes on the Files tab. To reuse a recent entry, click it in the Named box or the Search for the word(s) box.
To search for files by file name, in the Named box, you can do any of the following.
You can type Example
Partial file names Type region to find all files with names that include "region."
File name extensions Type *.txt to find text files.
Wildcard characters To find only file names that end with "region," type *region. Or type gr?y to find instances of both "gray" and "grey" in file names. Use an asterisk (*) to match any number of characters, or use a question mark (?) to match any single character.
To search for files that contain a specific word or have specific text properties, in the Search for the word(s) box, you can do any of the following to locate a file.
To find Use this operator Example
Any single character ? Typing s?t finds "sat" and "set."
Any string of characters * Typing s*d finds "sad" and "started."
Note If files do not appear in the Advanced Find dialog box, the Integrated File Management component probably wasn't loaded during Outlook Setup.
Believe it or not, but those poor people who wrote the application Help Files expect people to make use of them.
