similar to: Count frequency of term in a specific document?

Hi, there. I need some help. Is there a way to count frequencies of terms in a document on Ferret? I know that Ferret has IndexReader#terms_docs_for method which counts all documents. I need to count frequencies of terms in a specific document. Some way?? -- Posted via http://www.ruby-forum.com/.

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

I would like to thank all the people who have contributed to this very fine project. Great work! I''ve encountered some strange 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''m fairly new to ferret / aaf and finding it much easier to use than HyperEstraier (which I migrated from). However, I am getting a few errors and I need to figure out if they''re problems with my usage of ferret or a bug I should report. I''m currently running Ferret 0.10.11 with acts_as_ferret (latest via svn external) and 3 times today I''ve seen the

In the O''reilly Ferret short cuts, I found very useful example for me. It explains how to make custom Tokenizer. But that book doesn''t explain how to make custom Filter. (especially, how to implement the #text=() method) I''m a newbee and I don''t understand how do I create my own custom Filter. Are there some good source code examples?? -- Posted via

Hey all, The frequency count returned by my ferret reader doesn''t decrement after I remove a documents with those terms. Using the example from http://ferret.davebalmain.com/api/classes/Ferret/Index/TermEnum.html the frequency increments after a document is added but stays the same after a document is deleted. index.reader.terms(:tags).each do |term, freq| "#{term} appears

Hello, I'd like to be able to retrieve the indexes stored copy of the document text and tried the following: terms = self.db.allterms() terms.skip_to('Q' + uri.encode('utf-8')) term = terms.next() doc = self.db.get_document(term[1]) print doc.get_data() I just wildly guessed that [1] was the docid, but of course it isn't. So the question is, how do I

I have a lot of crashes when I try to use term vectors. Here''s an example, which crashes pretty consistently. This problem seems to be somewhat sensitive to platform... people on other OS''s and ruby versions have reported no error. I have seen this with ferret 0.10.13 and 0.10.14 on debian stable using ruby 1.8.2, but I have observed the same problem on various other systems as

Hi, I need to check the uniqueness of an attribute (a doc number) using a condition (a specific year), I''ve found validates_uniqueness_of :number, but I need to tell it I just want to check a specific year. I''ve found :scope but I haven''t really understood it''s meaning, Can I scope on a specific year? Thanks, Enrico -- "The only thing necessary for the

Hi! Suppose I have many articles in a database and I want to know how many times each search term appears in each one of them. Where do I start? Thank you very much! David -- Posted via http://www.ruby-forum.com/.

Hi all, I've been toying with xapian (mostly using the Python bindings) and I think I've hit a bug in the TermIterator::skip_to() method (or maybe in QuartzAllTermsList::skip_to()). I've attached a c++ source file that demonstrates the issue. In short, if you have a WritableDatabase, ask for the all-terms TermIterator with db.allterms_begin(), and then skip_to() a word that is itself

Hi, I''ve been having a problem getting highlighting to work with aaf. I have a class defined as follows such: class Link < ActiveRecord::Base acts_as_ferret :fields => { :description => { :store => :yes } } end I get back the correct results when I do Link.find_by_contents, however, I''d like to highlight them. If I do something like iterate through the list of

Hi David again. I would say that Ferret works great with Rails. And now I am trying to create pagination. Because site could have millions of documents I need to create on page link something like "Page #100". Rather usual situation. But to create this links I need to know how many documents Ferret found in index. For now I am doing it with following code index =

I''m trying to generate a rails pagination helper for some ferret search results, and I need to know how many total matches there are to my search query. I don''t see an obvious way of finding this. Any help would be appreciated. Thanks, Carl Youngblood

Hi, I seem to be having trouble getting more than 10 hits from Index#search_each since upgrading to 0.10.2 (ie, this was working in 0.9.4). Maybe a bug, as the #search_each doesn''t seem to use the options parameter any more ?

Hi, I''ve upset Ferret (again). When searching for: "us military" -bomb I get the following exception: State Error occured at <except.c>:79 in xraise Error occured in index.c:2089 - stde_doc_num Illegal state of TermDocEnum. You must call #next before you call #doc_num If I drop the quotes around "us military", or drop "-bomb", it works fine. I

I have a few questions. Asterisk is a windows program why each time I try to find out how communicate with my Panasonic TDA 100 or with TDE 100 always read "use one card o use a box" why I can't use simply my network card, in the other side of Panasonic exist two types of cards one in TDA 100 with 2 trunks and in the other side TDE have internal Two trunks too.

I am writing an indexer that will crawl our web site. Following the recommendation here: https://trac.xapian.org/wiki/FAQ/UniqueIds I'm using the URL as the unique ID for each document. I see how to get a document from the xapian database if I know its URL, but what I need is also to be able to find out the URL from the document. Does this mean I need to store the URL in a value in
