This is definitely helpful. We can get rid of quite a bit of custom code we wrote and manually merge with each release. CC-
-----Original Message----- From: Doug Cutting [mailto:[EMAIL PROTECTED] Sent: Monday, April 11, 2005 5:30 PM To: [email protected] Subject: sorting search results Currently query filters generate a Lucene Query. But Lucene's search methods have other parameters besides a query. In particular, these can also be passed a Filter and a Sort. In part as a work-around, Nutch automatically converts Lucene query clauses with zero boost into filters. But there is currently no way to generate sorted results using Nutch's search API. To remedy this I propose that the QueryFilter API be changed to something like: public class SearchParameters { public BooleanQuery getQuery(); public void setQuery(BooleanQuery clauses); public Filter getFilter(); public void setFilter(Filter filter); public Sort getSort(); public void getSort(Sort sort); } public interface QueryFilter { SearchParameters filter(Query input, SearchParameters output) throws QueryException; } If no one objects I will make this change and update all QueryFilters in SVN. Then I will add a SortQueryFilter that permits clauses like "sort:date", and a DateRangeQueryFilter that uses Lucene's RangeFilter (generally much more efficient than a RangeQuery). Thoughts? Doug
