Hi, I am not sure if you are still searching the answer for your question. If so, then please read on...
You can get the DF & IDF for each of the query terms in the query as below.. IndexReader reader = IndexReader.open(FSDirectory.open(new File(indexDir)), true); //Create a FilterIndexReader to invoke the abstract methods FilterIndexReader filterIndexReader = new FilterIndexReader(reader); //Number of documents in the index int numDocs = filterIndexReader.numDocs(); //Iterate over each of the query words for(String queryWord : queryWords){ Term term = new Term(searchField, queryWord.toLowerCase()); int docFreq = 0; try { docFreq = filterIndexReader.docFreq(term); } catch (IOException e) { logger.log(Level.SEVERE, null, e); } //Calculate IDF double idf = 0.0; if(docFreq > 0){ idf = Math.log10((double) numDocs / docFreq); } System.out.println(queryWord + "\tDF -" + docFreq + "\tIDF -" + idf); } -- View this message in context: http://lucene.472066.n3.nabble.com/Getting-DF-IDF-tp547386p844962.html Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
