Hello, I''m a novice to ferret, so far only used it via acts_as_ferret. My question is about a recommended pattern for an ''advanced search'', which would be searching by all fields of a model and some fields from related models, with range search, expression search and wildcards. The kind of search in which a user is presented with a huge form that allows them to set

Up to now in my ferret development I have been using simple single-word strings as my search queries. I just now am trying to increase the complexity of my queries. When I was passing a single word with no spaces in my index searches, like so: count = index.search_each(''testing'') do |d, s| ... end everything worked fine. But now when I do something like this: count =

Hi all, I''ve recently started working with Ferret and I''m getting what seems to be slow searches. I have about 10000 documents in the index, with several fields per document, with some fields having an array of several values that are indexed. I am using a RAMDirectory to store the index for searching. When doing testing, I find that searches are reasonable at around .2 to

Hi. I didn''t notice if topic has already been discussed, but I was wondering if there was a way to make ferret match only part of a search term. My initial thought was some sort of filter, but I''m unsure of where to begin. An example in the comments of the acts_as_ferret tutorial at RailsEnvy (http://www.railsenvy.com/2007/2/19/acts-as-ferret-tutorial) suggests: To return the

Hi everyone, I''m pretty new to Lucene and Ferret, so I feel that this is most likely myself not completely understanding the correct way to do this. I haved indexed ~2200 text files (of various sizes), and I am now running searches on the index to get a feel for Lucene and Ferret. In my first program, which is using Lucene I search for ''influenza'' and get the

Hello, I am exploring acts_as_ferret, and the first question that pops to mind is scoping, i.e. how to restrict searches in various ways. For example, I have a Post model with title, content, and user_id as attributes, and I want users to be able to search through their own posts only. Normally, of course, I would do Post.find(:all, :conditions=>["user_id=?", current_user],

Hi,David Can you give me an example of how to add analyzer to ferret to Asian languages? My web application will have to support multi language search,which means,for example,both Chinese and English will be searched through the form. Currently,I have decided to use the simple token principles,which means that every Chinese character will be a token,although this is not so well in some

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

Hi, I''m using ferret and running into troubles with it seg faulting during searches. The index I''m searching is static and is only updated in an offline way once every couple weeks. The segfault isn''t deterministically reproducible, but if I hammer ferret hard enough I can reliably get it to crash. The problem seems to have something to do with how memory is shared

I''d like to get the following behavior: 1. Stemming. The search is on a database of summaries of California legal cases. Things like a search for "thermal image" needs to hit "thermal imaging." 2. Stop words. Searches for "failing to instruct the jury" should come up with hits on a search for "fail to instruct." 3. Case-insensitive. What I

I''m trying to use the Ferret DRB server to avoid concurrency issues when using multiple mongrels. I can successfully add and edit data on my index via the DRB server, however, when I search the index, I get the following error: DRb::DRbConnError (DRb::DRbServerNotFound): /usr/lib/ruby/1.8/drb/drb.rb:1647:in `current_server'' /usr/lib/ruby/1.8/drb/drb.rb:1709:in

Hi list, I''m new to ferret and I wonder what is the best way to search if I know one fields id and want to search on its content. I have experimented with FilteredQuery but I don''t know if this is the best way. Eg. index = Index::Index.new(:path => ''/tmp/all'') @dbh = Database.instance.connect result = @dbh.exec("SELECT pk_fulltext_id, fulltext_text

Hello, I''m a new user of Ferret, so this might be a silly question. I was wondering, where can I find details about search memory usage? I read the O''Reilly booklet + googled but couldn''t find much info. There is a good explanation of how memory is used at indexing time [bound by, amongst other things, :max_buffer_memory and :max_buffered_docs]. But how does it work

I am seeing trouble with searches for ''you'' not returning anything. It appears that ''you'' is a stop word to the standard analyzer: require ''rubygems'' require ''ferret'' index = Ferret::I.new(:or_default => false) index << ''you'' puts index.search(''you'') returns

Hello ferret users, I have a problem with ferret dropping stored fields in the index. Not all fields I want to store get stored, so they can be searched, but can''t be retrieved in a search.

Lucene has a syntax "foo bar"~10 for finding foo within 10 words of bar. Does ferret support this feature? (the ~ is used for fuzzy queries) Does rdig? This could be a deal breaker for me ''cos I really need proximity searches -- Posted via http://www.ruby-forum.com/.
