Ferret fuzzy matches

Ruby Apps Ferret

Hi guys,

Is there some way of getting ferret matches string, when i do a fuzzy
search?

The scenario is this:

  1. The user search for ‘show’
  2. Nothing was found
  3. So I do a fuzzy search, passing ‘show~’
  4. It gives me somes results, most of all was matched with ‘showcase’
  5. So I want to tell the user that: Nothing was found with ‘show’,
    didn’t you mean ‘showcase’?

So, how do i get the ferret matches string, that was ‘showcase’ in that
scenario?

Thanks in advance,
José Valim

I’ve found out how to do that:

You have a class ‘Class’ with acts_as_ferret, so do that:

queryObj = Class.aff_index.ferret_index.process_query(@query_string)
searchObj = Class.aaf_index.ferret_index.searcher

query_results = queryObj.terms(searchObj).collect! {|item| item[:text]
}.uniq

query_results.is_a?(Array) => true

right, however I doubt this kind of direct access to Ferret’s searcher
will
work with aaf’s DRb server.

You should add a method like ‘matching_terms(query_string)’ to aaf’s
LocalIndex class to encapsulate above code, so you can call it across
the DRb connection.
