Ferret talk - Aug 2006 - acts_as_ferret to search partial phrases and fuzzy

Hi All,

I was wondering if anyone had experience of extending AAF plugin for 
Rails to implement a broader query ?

The documentation and the demo provided  on the 
http://projects.jkraemer.net/acts_as_ferret/ wiki seems to only match 
full text queries, or partial when using a * wildcard.

Ideally, I am trying to acheive something similar to the following 
(pseudo code):

  def search
    @query = params[:query] || ''''
    unless @query.blank?
      @results = Content.find_by_contents @query
      if @results.empty?
        @results = Content.partial_word_search @query
        if @results.empty?
          @results = Content.fuzzy_word_search @query
        end
      end
    end
  end

I realise I could probably achieve something like this by changing 
http://wiki.rubyonrails.com/rails/pages/HowToIntegrateFerretWithRails to 
meet my needs, but I quite like the indexing elegance provided with AAF, 
and don''t want to have to reinvent the wheel.

If anyone has experience or pointers that would be great!

Apologies for posting on the ferret list for a rails-ish problem, but 
searching the archives seemed to show most of the questions end up here!

Thank,
Paul

Hi Paul!

By default, aaf uses the stock Ferret QueryParser to parse queries
handed to find_by_contents. You have the full power of the Ferret Query
Language, including fuzzy search and friends.

However, if you give find_by_contents a Query object, this query will be
taken as is. 

So the easiest way to use aaf with custom queries would be to build those
queries outside aaf and use them with find_by_contents.

Does this already solve your problem ?
