Suppose I have a custom sorting 'DocScoreComparator' for computing distances on each search hit from a specified coordinate (similar to the DistanceComparatorSource example in LIA). Assume that the 'specified coordinate' is different for each query. This means a new custom comparator must be creat

I see you already got 2 answers. However, judging from your source, it looks like you are really using the .Net port of Lucene, so a better place to ask would be the lucene.net mailing list. Otis - Original Message From: Marcus Falck <[EMAIL PROTECTED]> To: java-user@lucene.apache.org

Re: Boost problems

Document boosts are folded into the individual fieldNorms when the document is indexed -- they are not accessible from the Document object returned after doing search. This is mentioned in the javadocs for Document.getBoost ... at least it is in 1.9, I'm not sure about 1.4. : Date: Wed, 17 May

RE: Changing the scoring (newest doc date first)

When you write your query, you can add a date range with a boot factor for this field, i.e boost y a factor x the documents that have a date of today, boost by x-1 the documents from the past wee, boost by x-2 the documents from the past two weeks, etc'. This will not be a perfect sort on the dat
