Hi, I am interested in writing a plugin, where the recency of the document, would also be a determinant as far as relevance/scoring is concerned. I don't want to sort by date, but would rather like to boost the score for pages which are most recently indexed.
Have tried adding range queries using a custom query filter, which creates queries of the form - <query> AND +(date:[20071215 TO 20071218]^3.0 date:[20071201 TO 20071214]^ 2.0 date:[20071103 TO 20071201]^1.5 date:[00000000 TO 20071102])^1.0 But I am not sure whether this is a good way or whether including date range clauses would have an adverse impact on performance. Am I missing something? Is there a better way of doing this? Any help would be much appreciated. Regards, Chris
