search for: booleanqueries

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

Okay in this plea for help I''m going to repeat some of what i posted before but with a larger amount of background info in the hope that i can get a decent grip on ferret before it wriggles away.. Firstly, what does installing the acts_as_ferret plugin actually do? I install it and add it to my model and then the index is automatically generated and a few methods are added to it and

Up to now in my ferret development I have been using simple single-word strings as my search queries. I just now am trying to increase the complexity of my queries. When I was passing a single word with no spaces in my index searches, like so: count = index.search_each(''testing'') do |d, s| ... end everything worked fine. But now when I do something like this: count =

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(

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 am trying to build up a filtered search using the logic below. bq = Ferret::Search::BooleanQuery.new bq.add_query(Ferret::Search::TermQuery.new(Ferret::Index::Term.new("section",section.downcase!)), Ferret::Search::BooleanClause::Occur::MUST) filter = Ferret::Search::QueryFilter.new(bq) @vobjects = VoObject.find_by_contents(search_input,:filter => filter, :sort

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

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. Then i get two temp x''s and y''s and search for all results that are within the box, see code below. Problems start to occur when i search on big distances so for

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
