IBooks PDF "whole word" search?

Question

Hey gang-
Love the new PDF features in iBooks. I've moved most of my frequently referenced work PDFs to my iBooks library. But iBooks seems to lack a "whole word" search capability. Am I missing something?
I need to be able search such that a Search for "part" does not also return "particle" or "participle", etc. I tried quotes and that didn't do it. Any way to do this?
Thanks!
Dave

Assuming you are on 10g:
with t as (
           select 'old county rd' address from dual union all
           select 'old church rd' address from dual union all
           select 'oldie rd' address from dual union all
           select 'Harold rd' address from dual union all
           select 'first street old' address from dual union all
           select 'new old church rd' address from dual union all
           select 'new-old church rd' address from dual union all
           select 'old-new church rd' address from dual
select  address
  from  t
  where regexp_like(address,'(^|\W)old(\W|$)','i')
ADDRESS
old county rd
old church rd
first street old
new old church rd
new-old church rd
old-new church rd
6 rows selected.
SQL> However, as you can see, the above sql will also return addesses where old is a word in a multipart words (e.g. new-old).
