similar to: Ferret against Java Lucene index

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 Folks, I''ve just released version 0.9.0. This latest version of Ferret is an alpha release. I have removed the old c extension and Ferret is now running on a fully ported C library. This has allowed some huge performance improvements both with regard to memory and CPU usage. There will probably be a few portability issues to start with. It has been developed on Linux so it should

We use Nutch and Lucene for our heavy duty text analysis jobs but I?m trying to use ferrret to do some experiments. I understood that Ferret used the same index format as lucene but I cannot look into a lucene index with ferret and cannot read a ferret index with luke (the lucene index browser). Am I doing somehting wrong or have the formats diverged? -------------- next part -------------- An

I would like to generate a Lucene index in Java (of plain text values only,) and be able to use that index in ferret. I''ve seen many mixed answers to this question, so I''m hoping some of you can help. Thanks! -- Posted via http://www.ruby-forum.com/.

Hi, I''ve listened in to this mail list for quite a while now but not doing anything with Ferret until I was ready to incorporate it. I''ve used Lucene for years, but not Ferret. I downloaded and installed the ''bleeding edge'' version (lets call it 0.10.9.1). There appears to be a significant re-working of the API happening. It all looks good. But there

Hi all, Having problems trying to get Ferret to read an index generated by Lucene. Am I right in thinking Ferret should be able to read a Lucene generated index no problem? Using the code snippets detailed in http://www.ruby-forum.com/topic/64099#new Any advice gratefully received. Many Thanks, Steven -- Posted via http://www.ruby-forum.com/.

Lucene has a syntax "foo bar"~10 for finding foo within 10 words of bar. Does ferret support this feature? (the ~ is used for fuzzy queries) Does rdig? This could be a deal breaker for me ''cos I really need proximity searches -- Posted via http://www.ruby-forum.com/.

I jut noticed this example in the lucene documentation*: title:(+return +"pink panther") I have been using this syntax: +title:(return AND "pink panther") Seemingly with success. Are both acceptable? I couldn''t find any documentation on "the plus sign" itself. Thanks for any pointers. John

Hi List, I''ve took some time and made some tests on the performance of java-lucene, hyperestraier and ferret as Dave encourages the community of ferret to do so. Quite intersting numbers. Ferret indeed deserves to be called a high-performance port!! It''s MyFirstBenchmark ( http://ferret.davebalmain.com/trac/wiki/MyFirstBenchmark ) so please don''t be too cruel on

hi, i''ve to choose a search engine for a medium-big site with a lot of searches and inserts at the same moment, do you suggest me something? i''m thinking about ferret, but i read that it has some problems with this king of "work" :( -- Posted via http://www.ruby-forum.com/.

Recently I''ve been revisiting some of my search code. With a greater understanding of how Java Lucene implements its search methods, I realized that one level of abstraction is not present in the Ferret classes/methods. Here are the relevant method signatures: Ferret''s search methods: in Ferret::Index::Index: search(query, options = {}) -> returns a TopDocs

Hi ferreteers, I came across a segfault in the query parser. It had already been reported[1] and fixed[2], but it can lead to a denial of service. If you use Ferret anywhere that you allow users to execute queries, those users can crash your Ruby process with a specially crafted query. I''m sure you''re all using Monit or something for your Rails or drb processes, so

Whats the relevance of score given by ferret? -- Posted via http://www.ruby-forum.com/.

Anybody who knows whether ferret or acts_as_ferret support wordsegment search? like what lucene can done. I wanna know,if not i will use lucene instead of this can''t found relevant documents on this aspect in ruby -- Posted via http://www.ruby-forum.com/.

Hello, does anybody know how to implement a "Did you mean ...?" like Google with act_as_ferret? I think this is a possible way: 1. Generate a keyword-list (this is my difficulty. I don''t know how to build such a list from the index) with no stop-words from the first index. e. g. (car, ship, plant, house) 2. Build a second index from this word-list where we store the word in

Hello. I''m the author of DataMapper (http://datamapper.org), and am trying to choose what Full-Text-Indexing engine/plugin I want to include by default. I was hoping you guys could help. :-) Sphinx comes highly recommended, but without live index updates, it just doesn''t seem practical for most of my work. I''m most experienced with Solr, but the whole HTTP::Request and

Hi there, What''s the current status of the Windows port? I may be in a position to lend a hand over the next couple of weeks - where should I start looking? And what''s the best way to get SVN HEAD? This happens: $ svn checkout svn://www.davebalmain.com/ferret/trunk ferret svn: Can''t connect to host ''www.davebalmain.com'': Connection refused --

Hi folks, This latest release of Ferret has a lot of improvements. There have been substantial improvements to performance. Try it for yourself to see. I won''t be publishing any numbers just yet. I will say though that it''s still about 2-4 times slower than Lucene with the extension installed. There is also some performance improvements in the pure Ruby version if you

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:

Hi everyone, I''m pretty new to Lucene and Ferret, so I feel that this is most likely myself not completely understanding the correct way to do this. I haved indexed ~2200 text files (of various sizes), and I am now running searches on the index to get a feel for Lucene and Ferret. In my first program, which is using Lucene I search for ''influenza'' and get the
