I just did a bible search on the word "holy" in the OT including "all bibles", but strangely it did not include the Tanak in its results. I was particularly interested in that translation since I keep it linked to my BHS. That way I could find all of the Hebrew words which were translated as "holy" whether it was the standard קדשׁ or something else (what? – apparently not).
BTW: I was interested in whether it was used of being holy to anyone or anything other than Yahweh. It is used otherwise only as being "holy to Aaron."
