Hi, I'm working in an industry which is fairly time sensitive, and older documents are inherently less valuable. I'd like to be able to "weight" the score of search results, so that older documents score lower. I don't just want to sort by date, though - I'd still like results to be ordered by score, just an "adjusted" score.
I've read the excellent LIA, including the chapter on custom sort methods, but from what I can tell that still only implements a sort on one field - I really want to be able to sort on a "blend" of fields (one of this is the actual document score). Could anyone suggest how I could implement this? I considered explicitly weighting the documents with a function of their date at index time, but this would mean the "weight" of the new documents would have to increase exponentially over time, and I suspect things would get messy! (Our dataset is around 250k documents, growing by a few thousand a month.) Cheers, Tim. ******************************************************************************** The information contained in this email message may be confidential.
