I am studying the possibility to use Lucene in order to build a matching system for a database of subjects. The subjects are stored in records of database with different fields like name, surname, address and I would like to build a proximity matcher that found an input subject in DB. The idea is to map the concept of document with the record , fields of record will be the fields of document.
The problem is that my matching system should be quite accurate and should be able to return only one subject matched (the most near to the input) and no subject matched in other cases. I am not able to find a valid rule for the No-matching. Is it possible to find a rule based on Score that tells that the subject in input is not near enough to the subject in DB , so it should not be matched? Is it possible to find a minimum score for this purpose? Any suggestion will be appreciated. ciao mauro
