RE: Is it possible to create an index with lucene core version 3.3+ by using Version.2_3 that I can then open an index with the original lucene core 2.3 version?

Hi, No, its not possible. The Version.LUCENE_23 param passed to several Lucene components is only to emulate behaviour on analysis (like tokenization rules) or specific settings from previous versions. The indexes created by IndexWriter can only be read by same or newer versions. With Lucene 4.0'

Re: Question about CustomScoreQuery

I can't explain this. Can you get at an oal.search.Explanation? You could write your own CustomScoreProvider - that might help you to double check what is being passed to it, and/or allow you to provide your own calculation. -- Ian. On Thu, Feb 16, 2012 at 8:32 PM, Dominika Puzio wrote: > He

Re: Top matched data should be on Top

Your example is hard to follow - too many words in the query and the docs. Have you looked at the output from IndexSearcher.explain()? If you don't like how lucene is scoring things you can write your own implementation of Similarity. -- Ian. On Sun, Feb 19, 2012 at 5:08 AM, A Z <4azfri...@gm

Re: StandardAnalyzer and Email Addresses

Are you using StandardAnalyzer in 3.1+? You may want to use ClassicAnalyzer instead. I can't see where in the 3.5 javadocs it says that email addresses are recognized, but it does sound vaguely familiar. -- Ian. On Thu, Feb 16, 2012 at 5:18 PM, Charlie Hubbard wrote: > This is a pretty simpl

RE: Indexing 100Gb of readonly numeric data

Hi Pedro, Maybe have a look at Hadoop / JAQL / HBase? For this "simple" setup it could be a scalable and simple solution (with additional aggregation functions). Best Ralf -Original Message- From: Pedro Ferreira [mailto:psilvaferre...@gmail.com] Sent: Mittwoch, 15. Februar 2012 23:18

Re: Index Merging

There is nothing in core lucene to do this and I don't recall seeing anything in contrib. One approach would be to loop through all the docs in the second index deleting them if present in first index, commit that change, then merge the two indexes. -- Ian. On Mon, Feb 20, 2012 at 11:58 AM, Kar

Index Merging

Hi to you, i've got a question concerning the merge of multiple indexes... Suppose we have two indexes which contain the same content ...than the result of a indexMerge is to have an index which contains the result doubled..ok so far so good ... But is there any chance/configuration that Lucen

RE: How to separate one index into multiple?

There is also MultiPassIndexSplitter, and PKIndexSplitter in contrib/misc. PKIndexSplitter is very easy to use (one of its ctors supports passing a Filter, all documents not matched by the filter are landing in second index, all documents matched by the filter in the first). This splitter is way mo

RE: Multiple CFS files are generated

Hi, The default was and is always to create CFS files. Since recent versions of Lucene it only changed a bit that CFS files are generated only for segments smaller than 10% of the total index size. You can change those settings (e.g. disabling CFS files completely) by setting the correct settings

Multiple CFS files are generated

Hello all, I am using Lucene 3.5.0 with all default options. I have not done optimize (forcedmerge). I could see multiple CFS files created as part of the index even though i haven't opted for. Could anyone tell me the reason. _4xq.fdt _4xq.fdx _4xq.fnm _4xq.frq _4xq.prx _4xq.tii _4xq.tis _4xq.
