Full text search - acts_as_ferret, mysql

Hi everyone,

I started developing an app that at some point will recevive as input
param a file containing an article (txt, .doc … not sure yet). And
based on some predifined words, sentences, phrases (stored in a table)
I want to be able to assign a score to the received article. This is
going to be my first project of this type so, any ideeas on how to
pursue this!!!..
– how should i store the predifined term (words, senteces, phrases),
each term per record (in tblterms)… one record and all the term in
blob field?!!?

… anyone worked in something similar?! All and any help is
appreciated.

Thank you,
