I think the TermFreqVector (reader.getTermVector) has the info you want per document. You will need to sort it by frequency to get the top terms in each document. It doesn't give you the wi, just tfi, but the whole score is implied by the fact that you have the top 10 documents, I think.

So if I get 10 Documents back from a search and I want to get the top 5 weighted terms for each of the 10 documents what API call should I use? I'm unable to find the connection between Similarity and a Document. I know I'm missing the elephant that must be in the middle of the room. Or maybe it's not there. Is what I'm trying to do do-able?

Hi, DefaultSimilarity uses exactly this weighting scheme. Makes sense since it's a pretty standard relevance measure...

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] --------------------------------------------------------------------- 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]
