basically, yes.

You can tell acts_as_ferret what analyzer to use with the :analyzer
option in the second options hash:

class MyModel
   acts_as_ferret { :fields => { ... } }, { :analyzer =>
RegExpAnalyzer.new }

end

background info: the first options hash are acts_as_ferret options, and
the second options hash is passed through to Ferret''s Index class.

Hello everyone!

I use the ferret as the following:
acts_as_ferret :fields => [:subject, :body], :analyzer => 
Ferret::Analysis::RegExpAnalyzer.new(/./,false)

when i input the english word to search, it''s so cool and so soon to
got
the result! but when i input the chinese words to search, the ruby 
allocate all the memory and the computer has no response, after a long 
long time wait, there''s a exception: failed to allocate memory! In the 
log file: Adding field body with value ''????'', it''s
true that ferret add
the chinese text into the index, but i can not search chinese words!

I don''t know how to deal with this!

in environment.rb, i add the following code
$KCODE = ''u''
require ''jcode''
ENV[''LANG''] = ''en_US.utf8''
require ''acts_as_ferret''

in my model, topic.rb
acts_as_ferret :fields => [:subject, :body], :analyzer =>
Ferret::Analysis::RegExpAnalyzer.new(/./,false)

it doesn''t work when i input the chinese word to search!

I don''t know how to do!

to make aaf use your analyzer, please format the call like this:

acts_as_ferret { :fields => [:subject, :body] }, 
               { :analyzer => Ferret::Analysis::RegExpAnalyzer.new(/./,false)
}


I''m seriously thinking about an API change because people always mix 
up the two hashes.

i would also be very grateful as well if someone could provide an 
analyzer for chinese text, or some hints how to build one. the 
StandardAnalyzer ignores all chinese glyphs.
cheers, phillip
