aligning Ferret''s IndexSearcher.search API with Lucene''s
Recently I''ve been revisiting some of my search code. With a greater
understanding of how Java Lucene implements its search methods, I
realized that one level of abstraction is not present in the Ferret
classes/methods. Here are the relevant method signatures:
Ferret''s search methods:
in Ferret::Index::Index:

ActiveRecord callbacks not happening
Hi,
I have a model class like so:
class Candidate < ActiveRecord::Base
validates_presence_of :name
@@index = FerretConfig::INDEX
def self.after_destroy
puts "Ferret: after_destroy called"
@@index.query_delete("+id:#{self.id} +ferret_class:#{self.class.name}")
optimize_index
end
end
But when I delete a record, the after_destroy is never called.

Ferret 0.10.2 - Index#search_each() and :num_docs
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 ?
Thanks,

Multiple indexes?
Hi,
I''m indexing records from different database tables and they have
identical column names in many cases. Does this mean I have to create
different indexes for each table?
TIA,

Get number of found documents
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

Sorting the Result
The document describes
search(query, options)
sort: An array of SortFields describing how to sort the results.
I have created index with two fields: ''file'' and ''content''
When I give SortField name as ''file'' while searching, it results into
error.
The exact command given by me:
index.search_each("sleepless AND dreams", :num_docs

assert_template fails?
Hi All,
I have a seemingly simple problem - but can''t figure out the problem. I
have a simple functional test like so:
def test_should_show_search_dropdown
get :index
assert_response :success
assert_template :search
end
Inspite of having search.rhtml in /app/views/layout, it fails with an error:

pagination in acts_as_ferret
I''m just wondering where I would put the pagination for search results
when using "acts_as_ferret".
At the moment my search code is..
def search
@query = params[:query] || ''''
unless @query.blank?
@results = Tutorial.find_by_contents @query
end
end
Cheers

Some newbie questions
Hi all,
I''m newly discovering Ferret, and just did a crash course on Lucene to
(I get the concepts behind it). But I''m have a few doubts:
1. What is the ''recommended'' way of integrating Ferret into my app now?
The gem version or the plugin?
2. Where do I checkout the plugin from? Do I just copy the version on
the wiki?
Those apart, Ferret is really

adding a custom filter to the query
Hi all,
I''m trying to figure out how to add a filter into a search. I''ve
created the filter, basically copying the location filter from
http://blog.tourb.us/archives/ferret-and-location-based-searches. But
when I try to call Index.search and pass the filter in a hash with the
key :filter, I get back that it is expecting type Data, and so I''m at
a loss to figure out

Reverse sorting
I am getting strange results when I reverse sort a query. I am sorting
by date, but it doesn''t seem to be related to dates (I have tried just
integers). I also paginate the results. Items in the result set are
sometimes duplicated and the not ordered at all. When I try a
non-reverse sort I don''t see duplicates and the ordering is correct. Any
ideas what is going on? Thanks

Problems with Ferret in RForum
Hi,
I have been using Ferret on ruby-forum.com for a few days. While the
searching works with reasonable performance, there are a lot of problems
related to indexing. Sometimes the process hangs with 100% CPU usage,
sometimes it leaves Lockfiles in the directory (causing other processes
to fail while one ist still working), sometimes it even crashes with a
segfault.

How to get the count of matching documents
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.

Index Searcher Causes GC Memory Error: "irb: double free or corruption"
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:

Could not get all matched docs
Hi,
I used Ferret to build an index and try to search here.
But it looks like it always return only 10 matches results,
event the return number of search_each is more than 10.
Did I do something wrong?
------------------
n = index.search_each("ruby") do |doc, score|
puts index[doc][''file'']
end
print n
------------------
I can only see 10 lines'' output.

search speed eclipsed by retrieval speed
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

A couple of ferret 0.9.4 exceptions
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

ANN: acts_as_ferret
Hi all
This week I have worked with Rails and Ferret to test Ferrets (and Lucenes)
capabilities. I decided to make a mixin for ActiveRecord as it seemed the
simplest possible solution and I ended up making this into a plugin.
For more info on Ferret see:
http://ferret.davebalmain.com/trac/
The plugin is functional but could easily be refined. Anyway I want to share it
with you. Regard it as a
