THis might be a stupid question. When perform retrieval for a query, deos Lucene first get a subset of candidate matches and then perform the ranking on the set? That is, similarity calculation is performed only on a subset of the docuemnts to the query.
If so, from which module could I get those candidate docs, then I can perform my own similarity calculations (since I might need to rewrite the normalization factor, so only modify the "similarity" model seems will not work). Or, is there document describe the produre of how Lucene perform search? thanks xiangyu jin --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
