similar to: QueryParser clean_string ?

During our last week of Ferret / aaf usage (also our first week of Ferret / aaf usage), I have received 8 messages stating that our app encountered a Ferret::QueryParser::QueryParseException. For instance: A Ferret::QueryParser::QueryParseException occurred in foo#search: Error occurred in src/q_parser.y:279 - yyerror couldn''t parse query "com -- 404". Error message

Hello, I am trying to escape words for searching i.e., "hello". The key here is that the two L''s on "hello" are actually vertical bars. Is there a special function in Ferret or anywhere for that matter that will do the escaping of the Ferret special characters? Thanks in advance, Benjamin

Hi there, I am stomped as to why QueryParser''s parse method behaves differently between query ''a'' and ''b''. See http://pastie.caboo.se/private/4rlwrecyyow3yl6qtf4tq Could someone please help me understand why that is the case. p.s. I also found ''i'' produce the same behavour as ''a'' Cheers, Andy

Hi all, Thanks to the authors for the amazing work on Ferret! I have a question about setting up the standard operators on a QueryParser. I would like my parser to default to AND queries rather than the default OR. In Java I would simply do: QueryParser parser = new QueryParser("contents", new StandardAnalyzer()); parser.setDefaultOperator(QueryParser.Operator.AND); But I

I cooked up a little script to show what I mean. This doesn''t look right to me, but maybe I just completely misunderstand QueryParser. Same output on mswin32, unix, ferret 0.9 and 0.10 Cheers, Sam require ''rubygems'' require ''ferret'' p Ferret::VERSION # 0.10.6 index = Ferret::Index::Index.new() index << {:title => "Programming

I am having a bit of a problem with my search queries being parsed correctly it seems, and I wonder if anyone else has experienced this. I have written an index using StandardAnalyzer for analysis. I want to search that index by passing my user query through a QueryParser instance which is also using a StandardAnalyzer. However the resultant query does not seem to be a valid term query and

QueryParser fails badly allocating enormous amount of memory when processing query strings with special/accented characters. See: irb(main):002:0> require ''rubygems'' irb(main):003:0> require ''ferret'' irb(main):004:0> include Ferret irb(main):005:0> index = Index::Index.new irb(main):008:0> index << "something" # Now the error

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(

Hello, I have a field which contains integer values. How do I obtain the maximum value of the column? Benjamin

According to the following link: http://ferret.davebalmain.com/api/classes/Ferret/QueryParser.html :handle_parser_errors => true is enabled by default and seems to be in acts_as_ferret in class_methods.rb of the plugin. However, when I pass a special character as a query (e.g., !, -, <, >, etc) it throws an error and pukes. -- snip -- Error occured in src/q_parser.y:279 - yyerror

Hello, Is there going to be a native windows release for 0.11.6? Alternatively, if a new version is going to be released soon, will there be a release for windows of that? Thanks! Benjamin

Hi, I need to map words in a document back to there original word id''s in my database. For example, if I had the sentence "I eat food" and I was searching for "food" I would obviously get the document back as a result. For my particular problem I need to not only get the document id but also the id of the match. Suppose my original sentence was actually

Hey folks, Some good news. I''ve finished cFerret and it''s ruby bindings to the point where I can run all of the unit tests. I still have to work out how I''m going to package and release it but it shouldn''t be long now. If you can''t wait you might like to try it from the subversion repository. It''ll probably only work on linux at the moment and

I''m running from the trunk, and hitting road blocks no matter which way I attempt to search across multiple indexes. I tried a MultiSearcher, but I can''t pass a string for the search query ms.search "iraq" TypeError: wrong argument type String (expected Data) So I tried creating a QueryParser to pass, but I can''t get the fields from the reader

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

Hello, I am having trouble getting data ranges to work correctly. I am using the following command to load the db: index << {:title => row[7].to_i, :date => Date.strptime(row[3], ''%Y-%m-%d''), :page_id => row[5].to_i, :page => row[6].to_i, :content_type => row[1].to_i,

I just started using Ferret and I successfully indexed some documents. I can search this index using the following code: index = Index::Index.new(:path => path) index.search_each("something") do |doc, score| print "##{doc} #{index[doc][''url'']} - #{score}" print "\n" end However, when I try to use Search::Searcher and QueryParser

Hey guys, I''ve just released Ferret 0.10.7. It is still in beta but we are getting closer and closer to a 1.0 release. The main changes in this release are better handling of fields by the QueryParser. You can now give the QueryParser a list of fields that are tokenized so that only those fields will be analyzed in the QueryParser. This means that you can search untokenized fields for

Hi, I am trying to get sorting working. I have had success with numbers but when I try to sort my string fields nothing happens. I am using the following code: options = {} s = Search::SortField.new(''object_title'', :reverse => false) options[:sort] = s @index.search_each("my query",options) do |id, score| puts "-->Document #{id} found with a
