Using StemFilter with PhraseQuery
Hi,
I''m having difficulty getting the StemFilter and PhraseQuery to work
properly together. When I use a StemFilter with a PhraseQuery, searches only
work if the phrase consists of stems. For example, the search phrase
"reduces health care" will not work but the phrase "reduce health care" will
work even though the exact text "reduces health care" is

Problem with stemming and AAF
I''m sure I''m missing something completely obvious here, so I hope
someone can point me in the right direction!
I''ve implemented a basic search with AAF, which works as expected; I''m
running a ferret drb server, and using will_paginate to page results.
The code in my search_controller.rb:
search_text = params[:query] || " "

acts_as_ferret : cannot use a customized Analyzer (as indicated in the AdvancedUsageNotes)
Hi all,
I cannot make aaf (rev. 220) use my custom analyzer, despite following the
indications @
http://projects.jkraemer.net/acts_as_ferret/wiki/AdvancedUsage
To pinpoint the problem, I created a model + a simple analyzer with 2 stop
words : "fax" and "gsm".
test 1 : model.rebuild_index + model.find_by_contents("fax") # fax is a
stop word.

case-sensitivity of analyzer
Is there anything about this analyzer that says "case-sensitive" to you?
module Ferret::Analysis
class StemmingAnalyzer
def token_stream(field, text)
StemFilter.new(StandardTokenizer.new(text))
end
end
end
Just wondering how I can force my index to be case-insensitive.
Thanks,

Metaphone analysis
Not sure how much this will interest people but I don''t have a blog so I''m
posting something I threw together today cause I think it might be useful.
In what little free time I have I''ve been wanting to put together a
Rails/Ferret based restful dictionary. So I finally got a chance to get
started today so the first thing I wanted to do was implement a metaphone

Ignore apostrophes in words
Hi, I just started using ferret and the aaf plugin and it seems to work
quite nicely. However, my fields are very short (titles of music) and I
don''t think may users will be typing in apostrophes when they are
looking for something. Right now, for a simple document such as "what
i''ve done" I''d like it to be indexed as "what ive done" instead. Right

tweaking minimum word length?
Hi,
Can Ferret be configured to change the minimum word length of what it
indexes? Right now it seems to drop words 3 characters or less, but
I''d like to include words going down to 2 characters. How would I do
that?

ferret finds ''tests'' but not ''test''
Hello all,
Quick question (possibly!) - I''ve got a few records indexed and doing a
search for ''test'' reports in no hits even though I know the word ''tests''
exists in the indexed field. Doing a search for ''tests'' produces a
result. I would have thought that ''test'' would match ''tests'' but no such

Weird analyzer issue with the word ''fly''
Hi all
I''m using a_a_f in rails with a StemmingAnalyzer, in the index and in my
search. I got the idea from this topic:
http://www.ruby-forum.com/topic/80178
I''m having a problem with some search terms - i narrowed one of them
down to the inclusion of the word ''fly''. Can anyone give me any clues
at to what might be happening, or even how i can investigate?

Tokenizers?
Hi everyone. First a quick word - I am relatively new to Ruby and Ruby
on Rails, but I love learning about it and using it. Currently I am
working on extending Boxroom (file repository RoR app) for the CARE
Indonsia intranet, where I work as an intern. I am using ferret, and
it''s working great.
I noticed that if a file contains something like this

Indexing and searching across multiple locales
Hi -
I''m currently investigating support for Ferret and content that spans
multiple locales. I am particularly interested in using stemming and fuzzy
searches (e.g. with slop factor) across multiple locales.
So far I''ve followed the online docs for implementing a Stemming Analyzer,
and it is working for English terms just fine. I''ve also written a method to

Extending/Modifying QueryParser
Hi,
I''ve implemented synonym searching in my rails application but have
an idea I''d like to implement but can''t figure out how to do. The
idea is that I''d like to give the end user the choice on whether to
search for the synonym of a word or not. Preferably by extending the
query language to parse a construct similar to ''%word1'' and

Re TrixBox
Hey Guys
We are replacing a BM4 with a trixbox (asterisk) virtual numbers as the
customer wants to move the callcentre.
They are asking for an equiv to the ipview
I gather HUD may be or the panel view
The problem is that we need to see
(a) total calls in the queue
(b) calls for specific DID - How can you give 1 DID preference to another

Ferret::Analysis::StemFilter documentation bug
"nl" selects the dutch stemming algorithm, "no" selects the norwegian
(as one would expect).
there''s no inconsistency, which the documentation would suggest (using
"dut" and "nld" for dutch stemming, "nl" or "no" for norwegian).
this is on ferret 0.11.4 at least, i didn''t check earlier versions.
