search for: indexsearch

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

Here''s the deal: static TopDocs *isea_search_w(Searcher *self, Weight *weight, int first_doc, // OFFSET int num_docs, // LIMIT Filter *filter, Sort *sort, filter_ft filter_func,

...et classes/methods. Here are the relevant method signatures: Ferret''s search methods: in Ferret::Index::Index: search(query, options = {}) -> returns a TopDocs search_each(query, options = {}) {|doc, score| ...} -> yields to context w/ doc and score for each hit in Ferret::Search::IndexSearcher: search(query, options = {}) -> returns a TopDocs search_each(query, filter = nil) {|doc, score| ...} -> yields to context w/ doc and score for each hit Lucene''s search methods: in the interface Searchable: public void search(Query query, Filter filter, HitCollector results) pub...

My linux Ruby application is using Ferret 0.11.4. I created my own class IndexSearcher to contain the Searcher of multiple directories. If I do not have the searcher.close called, the end of runner/console or runner/server will pop out with system error: *** glibc detected *** irb: double free or corruption (fasttop): 0x0a51d6c0 *** ======= Backtrace: ========= /lib/libc.so.6[0x...

Hey.. i am just browsing through the lucene features and i''m wondering if this feature is available in ferret as well .. # multiple-index searching with merged results this would be nice, as i''m thinking about several indexes, as i am using a lot of wildcard queries for livesearches like google suggest. i think the performance would increase, if i split my rather big index in

I''m running from the trunk, and hitting road blocks no matter which way I attempt to search across multiple indexes. I tried a MultiSearcher, but I can''t pass a string for the search query ms.search "iraq" TypeError: wrong argument type String (expected Data) So I tried creating a QueryParser to pass, but I can''t get the fields from the reader

I was wondering if there was a good way to either balance the relevancy score with recentness of matching documents- or include the recentness in the score somehow? Thanks, Ben -- Posted via http://www.ruby-forum.com/.

...single searcher is there anyway to identify which index a resulting doc is stored in? i1 = Ferret::I.new i2 = Ferret::I.new i1 << {:id=>1,:text=>"random stuff"} i1.commit reader = Ferret::Index::IndexReader.new([i1.options[:dir],i2.options[:dir]]) searcher = Ferret::Index::IndexSearcher.new(reader) query = Ferret::Search::MatchAllQuery.new searcher.search_each(query) do |doc_id,score| puts reader[doc_id][:text] # Anyway to find what index this doc is stored in? end -- Posted via http://www.ruby-forum.com/.

Is it safe to open the index to do searches on while another process is writing to the index? -- Posted via http://www.ruby-forum.com/.

Hi, I''m having some trouble with ferret search_each. I''m posting rails'' script/console output, so I guess you can decrypt it: >> res = [] => [] >> index.search_each(''name: a*'') do |doc, score| ?> res << doc >> end => 50 >> res.size => 10 >> I''m guessing the ''=>50''

One other mod to Ferret I''ve found useful is to add the following line at the top of the each_hit() block in Search::IndexSearcher.search: score = yield( doc, score ) if block_given? This allows a block attached to a search call to adjust document scores before documents are sorted, based on some (possibly dynamic) numerical factors associated with the document, e.g. the number and importance of incoming links to the...

Hey folks, Some good news. I''ve finished cFerret and it''s ruby bindings to the point where I can run all of the unit tests. I still have to work out how I''m going to package and release it but it shouldn''t be long now. If you can''t wait you might like to try it from the subversion repository. It''ll probably only work on linux at the moment and

Hi, I have this maddening strange bug using acts_as_ferret. If I search for a given phrase (let''s say "xyz") I get one set of results (lets call them set A). I search for xyz again and I get set A again. I search for xyz a third time and I get a different set (set B). I can keep executing the search query and my result sets continue to cycle a-a-b-a-a-b-a-a-b. It''s

Hi Dave, I am using ferret at my site http://gifthat.com and I just had a few exceptions pop up. I don''t have a way to reproduce them, but my site just was listed on lifehacker.com and these issues have popped up under multiple concurrent users (only twice though which I think isn''t too bad). I am using two lighttpd instances both with read/write access to the index: 1) Error

Hello. I''m the author of DataMapper (http://datamapper.org), and am trying to choose what Full-Text-Indexing engine/plugin I want to include by default. I was hoping you guys could help. :-) Sphinx comes highly recommended, but without live index updates, it just doesn''t seem practical for most of my work. I''m most experienced with Solr, but the whole HTTP::Request and
