similar to: fuzzy-ness to searches

Hi there, I''d like to be able to tune the results of a Fuzzy search in a rails application. I''ve tried setting the following in my environment.rb file. Ferret::Search::FuzzyQuery.default_min_similarity = 0.75 Ferret::Search::FuzzyQuery.default_prefix_length = 2 When I go into the console, I can see those values as the default but when I run a search like

I just submitted this to Trac, including a proposed fix. I''ve never really used Trac before, so hopefully I did the right thing. Anyway, in case anyone else runs into this, the problem is that fuzzy search fails if some of your saved fields are larger than Ferret::Search::TYPICAL_LONGEST_WORD_IN_INDEX. This won''t happen in all cases where your fields are larger (for example,

Hello, My Ferret integration has gone quite well. I''m now returning all the results I need from two models using "id_multi_search" and combining the results in the view using a couple of partials. Is there any way that I can turn on fuzzy searching? Would fuzzy searching pick up basic spelling mistakes such as "Bnadit" instead of "Bandit" my experience

Hey, I''m probably just missing something really obvious but I''ve been stuck on this problem for a while now and I''m not getting anywhere. I have installed the acts_as_ferret gem, as well as ferret according to the tutorial on RailsEnvy. My model, controller, and environment.rb files have all been modified as per that turotial. However any attempts to use the

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

Hello. Forgive my ignorance if this has been covered. I searched through the archives and didn''t find anything. All the blogs, tutorials, documentation I''m reading on acts_as_ferret say that to use fuzzy searching, I simply append a ~ to my query. I''m using Ferret 0.11.3 and the newest (should be) acts_as_ferret plugin. I can only get perfect matches to show up

Hey guys, I wanted to share with you guys a detailed tutorial I just finished this weekend for using Acts_As_Ferret. http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial I started using Ferret and Acts_As_Ferret a few weeks ago, and I learned so much that I wanted to give back to the community by writing up a helpful tutorial that covers all the key topics in one

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

I''m trying to use Ferret to do fuzzy searches. If I use fuzzy search for just one word, it works fine: index.search(''name:gogle~0.4'') However, if I try to use a phrase, it doesn''t work: index.search(''name:"gogle search engine"~0.4'') On the other hand, I could do: index.search(''name:gogle~0.4 AND

I''m having trouble getting fuzzy searches to work with multiple search terms. Let''s say searching ''foo'' returns results, ''bar'' returns results and ''foo bar'' returns results. When I do this fou~ bar~ it returns nothing. This, however, works fine: fou~ bar I want the fuzzy search to apply to each word, and this seems to

Hi, everyone, Just wondering if someone had come up with a good way to do fuzzy searches if you use MySQL as your database (we tried switching to PostgreSQL, but that ended up adding even more problems). Ferret sounds great, but reading through the discussion it looks like we need to solve the problem of write conflicts. I just wrote a post in ruby-talk about using KirbyBase maybe to solve

There are certain queries that I can execute that will cause a completely repeatable segmentation fault at the point where the search or search_each leaves my control and goes into the ferret libraries. I tried deleting my indexes and recreating them, and even so the exact same queries seg fault repeatedly after. Usually a one character change will make them succeed. Changing away from a

Hi folks, I''ve working and playing with acts_as_ferret and follow this fantastic tutorial: http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial When I try to implement the field storage tip, it crash. So, I try to make it via script/console: 1. I have a simple model called Articles: class Article < ActiveRecord::Base acts_as_ferret :fields =>

Hi, can someone give me a basic guide or any links to install the ferret plugin. Ive searched the forum but stil having problems. Im currently looking at this: http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial but having trouble. when i enter this: require ''acts_as_ferret'' in the environment.rb and run it, it stops my server from even working. also where do i enter

I have read the highlighting section at http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial#highlighting It mentions that for highlight to work I must have {:store => :yes}. However it also mentions that only "small" fields should be stored. My question is how small is small enough. I have a site where events information is maintained. I have events title and events

Hi, I''ve got a question about FuzzyQueries. Say I''m doing a search for people by name, and I want to allow fuzzy results if there aren''t enough hits with a regular query. This is easy enough; just redo the search with the fuzzy query if original_results.total_hits is less than some threshold. However, I would like the exact-match results to have a higher score

This may be offtopic to Rails, but what are people doing to find records based on fuzzy string matches? For example, if you wanted to find a Person with name "David Heinemeier Hansson" but searched using the string "Dave Hansson". Currently I am find_by_sql that calls the PostgreSQL function "levenshtein(string1, string2)" which returns results with a score

I''ve read the Rails Envy AAF tutorial at http://railsenvy.com/2007/2/19/acts-as-ferret-tutorial and its given me some really good ideas. My problem lies in having AAF search the target Model''s child tables. I have no problem at all doing something like: acts_as_ferret :fields => [:title, :update_collection, :member_name] def member_name return

Hi I am pinging to find out if there is any interest to mentor this proposal for GSoC this year? I've submitted a draft via the GSoC website. David, Vedant it would be great if I could get some advice on refining the goals and particulars of the implementation. The version we use internally is not performance oriented and will require refactoring. Here is a link to the draft document [1].
