Hi! I wanted to build my own custom Analyzer like so: class Analyzer < Ferret::Analysis::Analyzer include Ferret::Analysis def initialize(stop_words = ENGLISH_STOP_WORDS) @stop_words = stop_words end def token_stream(field, string) StopFilter.new(LetterTokenizer.new(string, true), @stop_words) end end As one can easily spot, I essentially want

Hi - I''m currently investigating support for Ferret and content that spans multiple locales. I am particularly interested in using stemming and fuzzy searches (e.g. with slop factor) across multiple locales. So far I''ve followed the online docs for implementing a Stemming Analyzer, and it is working for English terms just fine. I''ve also written a method to import data

Hello all, Quick question, I''m using AAF and the following custom analyzer: class StemmedAnalyzer < Ferret::Analysis::Analyzer include Ferret::Analysis def initialize(stop_words = ENGLISH_STOP_WORDS) @stop_words = stop_words end def token_stream(field, str) StemFilter.new(StopFilter.new(LowerCaseFilter.new(StandardTokenizer.new(str)), @stop_words)) end However when

Hi again, I''m using ferret to index source code - DamageControl will allow users to search for text in source code. Currently I''m using the default index with no custom analyzer (I''m using the StandardAnalyzer). Do you have any recommendations about how to write an analyzer that will index source code in a more ''optimal'' way? I.e. disregard common

Hi, I''m having difficulty getting the StemFilter and PhraseQuery to work properly together. When I use a StemFilter with a PhraseQuery, searches only work if the phrase consists of stems. For example, the search phrase "reduces health care" will not work but the phrase "reduce health care" will work even though the exact text "reduces health care" is

Hello all, I am new to the list, but I have been using ferret for a little bit already. I would first like to thank Dave for all his work on ferret. I had a few questions that I haven''t been able to figure out after messing around with ferret and going through the documentation. StemFilter ------ I am trying to improve the quality of my searches in context of the content of my

I''m sure I''m missing something completely obvious here, so I hope someone can point me in the right direction! I''ve implemented a basic search with AAF, which works as expected; I''m running a ferret drb server, and using will_paginate to page results. The code in my search_controller.rb: search_text = params[:query] || " " @products =

Hi all, I cannot make aaf (rev. 220) use my custom analyzer, despite following the indications @ http://projects.jkraemer.net/acts_as_ferret/wiki/AdvancedUsage To pinpoint the problem, I created a model + a simple analyzer with 2 stop words : "fax" and "gsm". test 1 : model.rebuild_index + model.find_by_contents("fax") # fax is a stop word. => I get a

Hi, I just started using ferret and the aaf plugin and it seems to work quite nicely. However, my fields are very short (titles of music) and I don''t think may users will be typing in apostrophes when they are looking for something. Right now, for a simple document such as "what i''ve done" I''d like it to be indexed as "what ive done" instead. Right

I''m using the custom stem analyzer: require ''rubygems'' require ''ferret'' include Ferret module Ferret::Analysis class FerretAnalyzer def initialize(stop_words = FULL_ENGLISH_STOP_WORDS) @stop_words = stop_words end def token_stream(field, text) StemFilter.new(StopFilter.new(LowerCaseFilter.new(StandardTokenizer.new(text)),

Hi, Can Ferret be configured to change the minimum word length of what it indexes? Right now it seems to drop words 3 characters or less, but I''d like to include words going down to 2 characters. How would I do that? Francis

I''m not on AAF. Can someone else help Raymond with an example?

Hi .. I tried to build some query objects to get some documents from my index.. without success.. Is something wrong here? q = Ferret::Search::BooleanQuery.new q1 = Ferret::Search::TermQuery.new(:type, "movie") q2 = Ferret::Search::TermQuery.new(:name, "Indiana") q.add_query(q1, :should) q.add_query(q2, :should) Indexer.index.search_each(q) do |doc, score| puts doc end 0

Today while compiling ferret I noticed there was a Portuguese stemmer being compiled. How do I enable it''s use for my index? Pedro.

I have got my database in Mysql. I used ferret to index a table with 10 million rows. On limiting the selection of data to 1000 initial retrieval, it takes 200 seconds but for the whole table it took more than four hours and after which i had to close my indexing application. I used the StandardAnalyser for it. There is no problem from the database side as retrieval of all the data in the table

Hi, I posted a Trac ticket about it, but I thought I''d ask the mailing list to reach more people. I''m using these filters together in my analyzer (with acts_as_ferret + Ferret 0.11.1). HyphenFilter.new( StopFilter.new( LowerCaseFilter.new( MappingFilter.new(

Hi, I''ve implemented synonym searching in my rails application but have an idea I''d like to implement but can''t figure out how to do. The idea is that I''d like to give the end user the choice on whether to search for the synonym of a word or not. Preferably by extending the query language to parse a construct similar to ''%word1'' and

I''ve successfully installed ferret and acts_as_ferret and have no problem with utf-8 for accented characters. It returns correct results fot e.g. fran?ais. My problem is with non latin characters (Persian indeed). I have tested different locales with no success both on Debian and Mac. Any idea?

Not sure how much this will interest people but I don''t have a blog so I''m posting something I threw together today cause I think it might be useful. In what little free time I have I''ve been wanting to put together a Rails/Ferret based restful dictionary. So I finally got a chance to get started today so the first thing I wanted to do was implement a metaphone
