Hey guys, I''ve been trying out ferret 0.9.3 on my powerbook this weekend and I''ve been triggering ''bus errors'' when using the Query API. If I programmatically build up strings, it works just fine. There''s some more information available in the trac ticket http://ferret.davebalmain.com/trac/ticket/62 Is anyone successfully using the Query API on

...e index is generated and searchable so i assumed that i would be able top use Ferret methods (other than the ones in acts as ferret)in my application. when i try the code at the bottom of this post i get the following errors (also in full at the bottom of post) NameError: uninitialized constant BooleanQuery So this means the rails/ruby/ is not seeing ferret right? so how do i get rials to be able to see ferret?

Hello all I finally caved in and decided I should build my own query instead of relying on QueryParser to do the job for me, but I''ve hit a strange problem.. Here''s how I build my query: #Main query query = Ferret::Search::BooleanQuery.new #Build query to match types typesquery = Ferret::Search::BooleanQuery.new @selected_types.each{|type| typesquery.add_query( Ferret::Search::TermQuery.new(Ferret::Index::Term.new(''type'', type)), Ferret::Search::BooleanClause::Occur::SHOULD ) } #Add types query to...

I want to compare two documents in the index (i.e. retrieve the cosine similarity/score between two documents term-vector''s). Is this possible using the standard Ferret functionality? Thanks in advance, Jeroen Bulters -- Posted via http://www.ruby-forum.com/.

I have to build an array through both activerecord and also through a ferret index. I was hoping to find a way of sorting the array as i combine the two so def advanced_search(search_text, store, format, sortby) # find items in ferret index items = Item.find_by_contents(search_text) # and now find all the items from a certain store or category items_from_sql = Item.find_by_sql("SELECT *

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 Indexer.index.search_each(q.to_s) do |doc, score| puts doc e...

Hi all, Is there a way to have searches no use some indexed fields, when processing a query? context: I have a model Foo that holds some information in two languages : - text1_nl, text2_nl, text3_nl and - text1_en, text2_en, text3_en Some other fields are common to both languages and indexed as well - first_name, last_name Depending on the visitor language choice I need to exclude the

I''m currently writing a system that stores user-created documents. Each user belongs to a specific group, and the system supports multiple groups. The thing is, my users want to be able to hide pieces of a document from other groups. So for example, lets say Joe of team A has written this document: "Hello all, our secret plan is finally complete! <private>We will begin

I''m not sure whether this is a bug or whether I''m simply expecting Ferret queries to work in a way other than they''re intended. I notice that if use a query like: (other_text:"Collaborative tools") AND NOT other_text:podcasts I''ll get correct search results. However, if I put parentheses around the second part, like:

Is there any somewhat standard way to remove or otherwise handle special or syntax characters from a user''s search, such as a colon? I was thinking maybe there was something akin to Ferret::Analysis::FULL_ENGLISH_STOP_WORDS, like Ferret::Analysis::FERRET_SYNTAX_CHARS, but no such luck. How are other folks dealing with filtering user input? John

Hi i''m using ferret to enable geographical postcode. I take a postcode and distance in miles from the user, strip off the outcode and then retrieve the associated x y coordinates in metres from the db.

Hello, I want to make a TAG CLOUD using ferret. How can i do so ? I would need to know the amount of keyword for every each words in the index. Thank you -- 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/.

Hi, I have a model class like so: class Candidate < ActiveRecord::Base validates_presence_of :name @@index = FerretConfig::INDEX def self.after_destroy puts "Ferret: after_destroy called" @@index.query_delete("+id:#{self.id} +ferret_class:#{self.class.name}") optimize_index end end But when I delete a record, the after_destroy is never called.

Hi, I upgraded from 0.3.2 to 0.9.0, and now my old search code doesn''t work anymore. I get a lot of ArgumentErrors, for example: "query.add_clause(Search::BooleanClause.new(query_parser.parse(term), Search::BooleanClause::Occur::MUST))" raises: ArgumentError (wrong number of arguments (2 for 0)) "index_searcher.search_each(query)" raises: ArgumentError

Hi, I''m confused about managing field boosting ... I have set the :boost for the :name field in my docs to 10, via :boost => 10 Then I performed a search for ''keith'' over all fields via with *:(keith*), expecting a doc with Keith in the :name field to come out on top. But another doc with Keith mentioned in other fields (:comments, :address) scored higher. I
