Hi, I have a couple of questions about how to alter the similarity scores. I need scores that can be thresholded, and whose thresholds remain stable even when I add documents to the IndexWriter. ie, identity should be a fixed value such as 1.0. I know that for efficiency reasons, Lucene doesn't do this. However, that level of efficiency is not as big a concern for me as getting a stable, thresholdable similarity score from, eg, "normal" cosine similarity. Is there a way to change the DefaultSimilarity trivally to get this feature, or is it a major overhaul? The searches from Lucene are being fed to another analyzer is why, so when the "identity" score changes by adding docs to the index, it messes up the rest of the processing.
The other question I had was about scoring via Latent Semantic Indexing. I read in the archives of this list from way back when that LSI was hard to integrate into Lucene. Is that still the case? I mean, from what I understand, it is just transforming the index in some way. Yours, --Asad. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
