parents: with an Indexed Folder Path, acts relative to the basename of the Path
so if you set up an Indexed Folder of:
C:\TMP\BRU\9000\
a parents:2 would find files/directories relative to the basename of the folder path,
so relative to the \9000\ directory,
so things like; \9000\DIR1\ & \9000\DIR2\ & \9000\abc.txt.
