-= acts_as_ferret
-
-This ActiveRecord mixin adds full text search capabilities to any Rails model.
-
-It is heavily based on the original acts_as_ferret plugin done by
-Kasper Weibel and a modified version done by Thomas Lockney, which 
-both can be found on http://ferret.davebalmain.com/trac/wiki/FerretOnRails
-
-== Installation
-
-=== Installation inside your Rails project via script/plugin
-
-script/plugin install svn://projects.jkraemer.net/acts_as_ferret/trunk/plugin/acts_as_ferret
-
-Aaf is is also available via git from Rubyforge:
-git clone git://rubyforge.org/actsasferret.git
-
-=== System-wide installation with Rubygems
-
-<tt>sudo gem install acts_as_ferret</tt>
-
-To use acts_as_ferret in your project, add the following line to your
-project's config/environment.rb:
-
-<tt>require 'acts_as_ferret'</tt>
-
-Call the aaf_install script inside your project directory to install the sample
-config file and the drb server start/stop script.
-
-
-== Usage
-
-include the following in your model class (specifiying the fields you want to get indexed):
-
-<tt>acts_as_ferret :fields => [ :title, :description ]</tt>
-
-now you can use ModelClass.find_by_contents(query) to find instances of your model
-whose indexed fields match a given query. All query terms are required by default, 
-but explicit OR queries are possible. This differs from the ferret default, but 
-imho is the more often needed/expected behaviour (more query terms result in 
-less results).
-
-Please see ActsAsFerret::ActMethods#acts_as_ferret for more information.

-Credits
-=======
-
-The Win32 service support scripts have been written by
-Herryanto Siatono <herryanto@pluitsolutions.com>. 
-
-See his accompanying blog posting at
-http://www.pluitsolutions.com/2007/07/30/acts-as-ferret-drbserver-win32-service/
-
-
-Usage
-=====
-
-There are two scripts:
-
-script/ferret_service is used to install/remove/start/stop the win32 service.
-
-script/ferret_daemon is to be called by Win32 service to start/stop the
-DRbServer.
-
-Run 'ruby script/ferret_service -h' for more info.

-    # if:: Can be set to a block that will be called with the record in question

-    #
-    # ferret:: Hash of Options that directly influence the way the Ferret engine works. You 
-    #          can use most of the options the Ferret::I class accepts here, too. Among the 
-    #          more useful are:
-    #
-    #     or_default:: whether query terms are required by
-    #                  default (the default, false), or not (true)
-    # 
-    #     analyzer:: the analyzer to use for query parsing (default: nil,
-    #                which means the ferret StandardAnalyzer gets used)
-    #
-    #     default_field:: use to set one or more fields that are searched for query terms
-    #                     that don't have an explicit field list. This list should *not*
-    #                     contain any untokenized fields. If it does, you're asking
-    #                     for trouble (i.e. not getting results for queries having
-    #                     stop words in them). Aaf by default initializes the default field 
-    #                     list to contain all tokenized fields. If you use :single_index => true, 
-    #                     you really should set this option specifying your default field
-    #                     list (which should be equal in all your classes sharing the index).
-    #                     Otherwise you might get incorrect search results and you won't get 
-    #                     any lazy loading of stored field data.

-# Ferret DRb server Capistrano tasks
-# 
-# Usage:
-# in your Capfile, add acts_as_ferret's recipes directory to your load path and
-# load the ferret tasks:
-#
-# load_paths << 'vendor/plugins/acts_as_ferret/recipes'
-# load 'aaf_recipes'
-#
-# This will hook aaf's DRb start/stop tasks into the standard
-# deploy:{start|restart|stop} tasks so the server will be restarted along with
-# the rest of your application.
-# Also an index directory in the shared folder will be created and symlinked
-# into current/ when you deploy.
-#
-# In order to use the ferret:index:rebuild task, declare the indexes you intend to
-# rebuild remotely in config/deploy.rb:
-#
-# set :ferret_indexes, %w( model another_model shared )
-#
-# HINT: To be very sure that your DRb server and application are always using
-# the same model and schema versions, and you never lose any index updates because
-# of the DRb server being restarted in that moment, use the following sequence
-# to update your application:
-#
-# cap deploy:stop deploy:update deploy:migrate deploy:start
-#
-# That will stop the DRb server after stopping your application, and bring it
-# up before starting the application again. Plus they'll never use different
-# versions of model classes (which might happen otherwise)
-# Downside: Your downtime is a bit longer than with the usual deploy, so be sure to
-# put up some maintenance page for the meantime. Obviously this won't work if
-# your migrations need acts_as_ferret (i.e. if you update model instances which
-# would lead to index updates). In this case bring up the DRb server before
-# running your migrations:
-#
-# cap deploy:stop deploy:update ferret:start deploy:migrate ferret:stop deploy:start
-#
-# Chances are that you're still not safe if your migrations not only modify the index, 
-# but also change the structure of your models. So just don't do both things in
-# one go - I can't think of an easy way to handle this case automatically.
-# Suggestions and patches are of course very welcome :-)

1	-= acts_as_ferret
2	-
3	-This ActiveRecord mixin adds full text search capabilities to any Rails model.
4	-
5	-It is heavily based on the original acts_as_ferret plugin done by
6	-Kasper Weibel and a modified version done by Thomas Lockney, which
7	-both can be found on http://ferret.davebalmain.com/trac/wiki/FerretOnRails
8	-
9	-== Installation
10	-
11	-=== Installation inside your Rails project via script/plugin
12	-
13	-script/plugin install svn://projects.jkraemer.net/acts_as_ferret/trunk/plugin/acts_as_ferret
14	-
15	-Aaf is is also available via git from Rubyforge:
16	-git clone git://rubyforge.org/actsasferret.git
17	-
18	-=== System-wide installation with Rubygems
19	-
20	-<tt>sudo gem install acts_as_ferret</tt>
21	-
22	-To use acts_as_ferret in your project, add the following line to your
23	-project's config/environment.rb:
24	-
25	-<tt>require 'acts_as_ferret'</tt>
26	-
27	-Call the aaf_install script inside your project directory to install the sample
28	-config file and the drb server start/stop script.
29	-
30	-
31	-== Usage
32	-
33	-include the following in your model class (specifiying the fields you want to get indexed):
34	-
35	-<tt>acts_as_ferret :fields => [ :title, :description ]</tt>
36	-
37	-now you can use ModelClass.find_by_contents(query) to find instances of your model
38	-whose indexed fields match a given query. All query terms are required by default,
39	-but explicit OR queries are possible. This differs from the ferret default, but
40	-imho is the more often needed/expected behaviour (more query terms result in
41	-less results).
42	-
43	-Please see ActsAsFerret::ActMethods#acts_as_ferret for more information.
