search for: mappingfilter

..._filter mf[:country] = country_filter # run the query with the filter index.search(query, :filter => mf) # filters can be changed and deleted mf[:category] = new_category_filter mf.delete(:country) index.search(query, :filter => mf) The other major addition is a MappingFilter (< TokenFilter). This can be used to transform your code from UTF-8 to ascii for example. I posted an example of how to do this earlier today. However, using the mapping filter you can apply a list of mappings string mappings rather than just character mappings. Obviously you could acheive this...

Hi, I''m working on a Ferret-based application which indexes content in all European languages. Thus, I have to deal with those funny European characters. After googling a bit, I decided to move on with a custom European analyzer based on MappingFilter, as suggested in the Ferret rdoc. Everything works fine with Ferret 0.11.3 on Mac OS X. But this application needs to run on both Windows and Mac OS X. Since there''s no mswin32 gem for 0.11.3, I decided to downgrade to 0.10.9 and replace MappingFilter with a custom-made filter as suggeste...

Hi all, I have indexed a huge amount of data with text from several european languages. In the index are values like Georg Friedrich H?ndel. I would like a search phrase like "Georg Friedrich Handel" to find records with the real spelling of H?ndel but it doesn''t seem to work. Can anyone give me an idea of what I need to do to make this happen. A bit lost here and

...9;',''?'',''?''] => ''y'', [''?'',''?'',''?''] => ''z'' } def token_stream(field, string) return MappingFilter.new(StandardTokenizer.new(string), MAPPING) end end And inserted this code at the end of environment.rb. Im my model: acts_as_ferret({ :fields => [ ''name'' ] }, :analyzer => PortugueseAnalyzer.new) But this did not work.... Can someone tell me what I did wrong ???...

Greetings, (using acts_as_ferret) So I have a book title "M?ngrel ?Horsemen?" in my index. Searching for "M?ngrel" retrieves the document. But I would like searching for "Mongrel" to also retrieve the document. Which it does not currently. Anyone have any good solutions to this problem? I suppose I could filter the documents and queries first which something

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

...icket 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( StandardTokenizer.new(str), mapping)), FULL_FRENCH_STOP_WORDS + FULL_ENGLISH_STOP_WORDS) ) The mapping filter maps pretty much all the french accents to the letter without the accent. So far so good. Only thing mi...
