Rails - Apr 2006 - Strench Error

I am new with ruby but something fishy with the array.
if I type
q=aa
puts INV_FILE_HASH[q]   # where INV_FILE_HASH is my hash function
I GET THE RESULT PERFECTLY HOWEVER,
query is user input and couldbe ''aa'' or ''aa
aa''
query = query.split(/ /)
 query.each { |q|
  if (q == ''and'')
    OP.push(''and'')
  elsif (q == ''or'')
    OP.push(''or'')
  else
    # q=aa at this point which is correct
    puts INV_FILE_HASH[q]    # prints out nil instead of values
  end
}

I get "nil" where the query is ''aa'' so the q is
''aa''.
 but if the query is ''aa aa'' than q first run is
''aa'' and second run is
''aa'' in first run it prints the result out but on second run
the result
is ''nil'' again. I can run 1000 run the first 999 is correct
but 1000th
run is nil again. what does realy cause this?

I found it, it was
query = query.split(/ /)
some reason when I change to
query = query.scan(/\w+/)
it worked HOWEVER
THIS TIME IT IGNORES MY PHARANTESIS, how can I scan so that it would 
take the pharanthesis as another piece of string ?
thank you
