Detect hyphen or underscore separated words
When using the bing-powered "work" search, I cannot find files whose names are separated with hyphens or underscores. For example, assume I have three files named "MY FILE", "THIS_FILE", and "THAT-FILE". If I type into the search box FILE then only the first one, named "MY FILE", will appear.
This is frustrating since some systems don't support spaces easily.
