[chord] are my assumption reasonable

Hi,
  I want to achieve multi key query.So I divide a data item(include
some words) into some keys.And then map these keys to different nodes.
  When people query part of keys,he will get many result.But only
those peers which result's number equal the people query number are
the right.Others are deleted.So people can query part of the keys.
  For example,people query two keys.He will get many results.But those
peers which satisfy these two keys at the same time are the right
peers.
  But I think this method of multi keys query will lead to increase
the load of the network obviously.I have no better idea.
  I am eager to get some good suggestions.Thanks a lot.

Sincerely
William
