Yes and no. If your indices contains the same kind of documents, scores are roughly comparable, with the comparability growing with index size (less chance of outliers skewing the scores). If your indices are dedicated to different resources (e.g. one for physics papers, one for biology etc.), then the scores between them will be very poorly comparable. > If so, what can I do to make the scores from multiple indices comparable? Wait for https://issues.apache.org/jira/browse/SOLR-1632 or ensure that the content (and sizes) of your indices are homogenous. - Toke Eskildsen --------------------------------------------------------------------- To unsubscribe, e-mail: java-user-unsubscr...@lucene.apache.org For additional commands, e-mail: java-user-h...@lucene.apache.org
