...trange results while examining the term frequency of one of my indexed documents. The indexed terms seem to vary for the very same document depending on the presence or absence of completely unrelated operations in the code, so the resulting term frequency changes, too. I repeatedly call ''index_reader.term_docs_for'' for the only document I''ve indexed in the snippet below, but depending on the presence of the statement ''dummy_count = 0'' or some formatting code for the output the resulting term frequencies change from correct answers to wrong ones. Sometimes t...

I am looking to have a number of categories populated from my results of a search. For example, searching on "sport" would display all results for sport. I want to also have a number of categories to refine the documents down. So by clicking on the "Fishing" category or the "Shooting" category, I would only see the results on sport around that category. Now for

I''m building my first Filter and I''m running into an issue with Ferret::Index::IndexReader#term_docs. As I understand it, index_reader.term_docs should return a term-document enumerator for the entire index: index_reader.term_docs => empty set However, I''m getting an empty set. Interestingly enough, the following: index_reader.term_docs_for(:name, ''coffee'') => lots of documents Is returning p...

Hello, I am currently using ferret 0.9.5 and acts_as_ferret 0.2.3 on windows XP All my unit and functions test that used to work before I installed ferret are erroring out. My index is on a model name Post, and it looks like all tests that contains methods which does CRUD to the Post model bombs out. Is there anything special I need to do before running unit and functional test? Thanks

I want to compare two documents in the index (i.e. retrieve the cosine similarity/score between two documents term-vector''s). Is this possible using the standard Ferret functionality? Thanks in advance, Jeroen Bulters -- Posted via http://www.ruby-forum.com/.

I want to correct spelling errors automatically. I have used search in the past where I can pass an argument through standard search to correct a word with up to 2 spelling errors for example or do the more Google like "Did ya mean?". In this case I just want to change it automatically and search. I am not too interested in specifying the number of characters it is out by. What is

...re two interesting additions to this release. You can now access the Filter#bits method of the built in filters so you can can use them in your own code, possibly within your own custom filters. For example you could implement a custom filter like so: class MultiFilter < Hash def bits(index_reader) bit_vector = Ferret::Utils::BitVector.new.not! filters = self.values filters.each {|filter| bit_vector.and!(filter.bits(index_reader))} bit_vector end end And you would use it like this: mf = MultiFilter.new mf[:category] = category_filter...

Hi i''m using ferret to enable geographical postcode. I take a postcode and distance in miles from the user, strip off the outcode and then retrieve the associated x y coordinates in metres from the db.

Hello, I need to be able to count the occurences of certain terms in the reults. Currently my setup is Ferret 0.10.1 aaf bleeding edge. results = VoObject.find_by_contents(query,:offset=>page, :limit=> 20,:sort => sort_fields) I use results.total_hits for pagination. This all works really nicely. However i need to be able to know how many occurences of certain predefined terms occur

Is there a fast way to determine how many documents a term occurs in, besides iterating through every document with TermDocEnum? -- Best regards, Stian Gryt?yr

Hi! First, thanks a LOT for ferret. The API and documentation is great. I''m trying to integrate ferret into a RoR app (DamageControl) and have run into a problem with locks. DamageControl consists of two processes that start up and run in parallel. The first one is the webapp (which is just a plain RoR app). The second is a daemon process that runs in the background. The daemon process
