Ferret talk - Dec 2007 - indexing tuples (example: "frog" => 123) as opposed to words

Hi,

I need to map words in a document back to there original word id''s in
my
database.  For example, if I had the sentence "I eat food" and I was 
searching for "food" I would obviously get the document back as a 
result. For my particular problem I need to not only get the document id 
but also the id of the match. 

Suppose my original sentence was actually represented as tuples where 
each word contains the word and an id number.  The new structure would 
look something like "(I => 1, eat => 2, food => 3)".  In this
case I
would actually like to not only get the document but also the document 
id number of the match, which in this case would be "3". Is there any 
way to do this in Ferret?

FYI, my goal is to be able to go back an locate the words matches for 
further analysis.

Any help would be greatly appreciated.  Thank you.

Hey ..

I''m not quite sure i fully understand what you''re going to
achieve, but
maybe TermVectors will help you.
