    OK, forgive my haste: the "set 'Saturation of color of text fill'
property to 0%" method i described above DOES NOT WORK as intended,
since the text can still be visible on a non-white background or if the
text frame is moved above some graphic, etc..

    thus, it looks like the 0% transparency method is still the leading
candidate for invisible but searchable text.
