If I have search results how can I calculate, using lucene's API, wi = tfi * IDFi for each document. wi = term weight tfi = term frequency in a document IDFi = inverse document frequency = log(D/dfi) dfi = document frequency or number of documents containing term i D = number of documents in my search result Thanks, Andrew --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
