Searching a Specific Directory, With a Keyword, Display Results

Does your keyword need to be in the file name, or in the contents of the file?
In either case, this is very easy to do in the Finder.
In a Finder window that is opened to the target folder, press ⌘⌥F to start a Finder Spotlight search. Then enter:

  • YourKeyWord
    OR
  • name:YourKeyWord
