Re: Grouping on multiple shards possible in lucene?

Thanks Mike. Actually, I think I can eliminate sort-by-time, if I am able to iterate postings in reverse doc-id order. Is this possible in lucene? Also, for a TopN query sorted by doc-id will the query terminate early? -- Ravi On Fri, Nov 16, 2012 at 9:40 PM, Michael McCandless < luc...@mikemccan

TokenStreamComponents in Lucene 4.0

Hi, I have recently updated to Lucene 4.0, but having problems with my custom Analyzer/Tokenizer. In the days of Lucene 3.6, it would work like this: 0. define constants lucene_version and indexdir 1. create an Analyzer: analyzer = new KoraAnalyzer() (our custom Analyzer) 2. create an IndexWriter

Re: Question about ordering rule of SpanNearQuery

Unfortunately, there doesn't appear to be any Javadoc that discusses what factors are used to score spans. For example, how to relate the number of times a span matches in a document vs. the exactness of each span match. -- Jack Krupansky -Original Message- From: 杨光 Sent: Monday, Nov

Re: what is the offsets and payload in DocsAndPositionsEnum for ??

A new postings format would be tricky because you have new attributes you want to index. The DocsAndPositionsEnum does have an attributes source, but this is not well explored, and there are known problems (they can't be easily merged in the composite reader case). So that's why I suggested packi

Question about ordering rule of SpanNearQuery

Hi all, Recently, we are developing a platform with lucene. The ordering rule we specified is the document with the shortest distance between query terms ranks the first. But there may be a little different with SpanNearQuery. It returns all the documents with qualified distance. So I am con

RE: German 'ue' -> 'u' conversion

Yes, that would solve my question 2. I can convert all umlauts to 'ue', 'ae', etc form before the tokens get to other filters and it should work fine. Thanks, Adam -Original Message- From: Igal @ getRailo.org [mailto:i...@getrailo.org] Sent: 19 listopada 2012 11:15 To: java-user@lucene
