Hi, all: I have wrote a demo patch for Backend for Lucene format indexes, Lucene version is 3.6.2. http://lucene.apache.org/core/3_6_2/fileformats.html Now, this demo patch just support the basic features in Lucene.

Hello, I have some ideas for packages that I want to provide on R-CRAN. One package alreads is working, but I have some warnings in when compiling. Also I don't know if the libraries in use are only working on Unix/Linux. So I have some general questions: - If I'm not sure if the code would also work on windows (needing some ceratain libraries or tools), would it be better to

Hi, What would it take to get the a Lucene.net index readable by Ferret? I know that there has been discussion on this before but I am trying to figure the actual amount of work (cost) would be required to get this done. Any help would be greatly appreciated. Benjamin

Hi, I am working on a project which has a large Lucene index in place. Can (any version of) Ferret be used against an index built using Java Lucene? Thanks, Eric

I found it quite fun to generate index by ferret. However, I had to use lucene now. Can I use the index that I''ve already done by ferret? ps. Lucene 2.2.0 vs Ferret 0.11.4 Thx! -- Posted via http://www.ruby-forum.com/.

Hi All, Hope all is going well. After being knocked out with the flu for a week I''ve been able to make some progress with porting the lucene highlighter to ferret. I''ve got a draft version available for perusal at: http://crafterm.net/ruby/highlighter/highlighter-ruby-0.1.tar.gz The port is pretty much a complete copy of the Java version at:

I haven''t dug into this yet, but wanted to report it. I''ve built an index with Java Lucene (1.9, from svn trunk) and then trying to search it with Ferret and getting this: /usr/lib/ruby/site_ruby/1.8/ferret/index/term_buffer.rb:31:in `read'': undefined method `name'' for nil:NilClass (NoMethodError) from /usr/lib/ruby/site_ruby/1.8/ferret/index/

Hi All, At the risk of starting a major flame war and giving Java player-haters more fuel for their ire, I''ve done a performance comparison between Ruby/Odeum and Lucene: http://www.zedshaw.com/projects/ruby_odeum/performance.html Please don''t take this as a "Java sucks Ruby rulez" posting, or that I''ve done any sort of scientific analysis here.

Hi all, I've been asked to prepare a comparison of Lucene/Solr and Xapian and I'm trying to find some differences between the two. I'm not that familiar with Lucene myself but I expect there are lots of people who will have looked at both before ending up on this mailing lists. Can anyone help? I'm looking for both differences between the two systems and perhaps the reasons

For a single server, is the Lucene backend now "better" than running a Solr server? -- Daniel

Hi Timo, As one who is interested in implementing FTS sometime in the future, I'm curious about what is in store as far as improvements go... Specifically, any plans for implementing immediate/automatic index updates at delivery time? The lack of automatically updated indexes is one downside for its implementation... Also, does the release of Solr 4.0 mean anything for the lucene library

Hi, What's the main difference between chert and flint? What above vs lucene? I am mainly asking about data structure (lexicon, posting list, document data), what's in memory, what's on disk, hash vs b-tree and reasons behind them. Any pointer is appreciated. Thanks!

Hi, I'm interested to implement the idea of using search indexes build by Lucene. I have some idea of how to do that. I'm currently studying the index format of both. I have written an application of search using Lucene and now I'll do the same using Xapian. then I'll check the details of those index format and then find how to convert Lucene index to Xapian one. Is there somebody
