those two facts together pretty much put the kibosh on doing this with a
searching through an entire branch, with an unknown number of levels, is
next to impossible using the adjacency data model (which is characterized by
the use of a "parentid" column)
if you were to switch to the nested set model (characterized by the use of
"lft" and "rgt" columns), things will go a lot easier for you, although i
can't help you with it as i don't do the nested set model
