MacOS – spotlight search for folder within finder

Use Unix find as follows

find . -maxdepth 1 -name config.txt -print

In Terminal, type man find for details.

If you do this often, you can make it into a shell function.

The Finder search box does not support wildcards. You can add additional criteria to narrow down your search, though.

1. Enter _doc in the search field to start a search.
2. In the bar that appears (showing "Search: This Mac" etc) click the plus sign button all the way to the right.
3. In the new row that appears, in the first combobox, select Name, then in the next one select Contains, then in the empty text box type _doc (without wildcards or the file extension).
4. Click the plus sign button all the way to the right of this new row.
5. In the first combobox of the second row, choose Kind. In the second combobox, choose Other. In the empty text box type xml (without the leading period).

This will narrow down your search to files whose names contain _doc and whose extensions are xml.
