I noticed that the :single\_index option is no longer listed in the  
documentation for AAF, specifically in lib/acts\_methods.rb [1]

Furthermore, after an upgrade from a rather old version of AAF, I notice  
that the index (after reindexing) is no longer in  
RAILS\_ROOT/index/RAILS\_ENV/shared, but instead split out into separate  
directories for each model. What changed?

Thanks,

[1] Notice it’s still listed as an option here:  
[http://actsasferret.rubyforge.org/classes/ActsAsFerret/ActMethods.html](http://actsasferret.rubyforge.org/classes/ActsAsFerret/ActMethods.html)  
but not at  
[http://projects.jkraemer.net/acts\_as\_ferret/browser/trunk/plugin/acts\_as\_ferret/lib/act\_methods.rb](http://projects.jkraemer.net/acts_as_ferret/browser/trunk/plugin/acts_as_ferret/lib/act_methods.rb)

:single\_index isn’t supported any more.

With current trunk the preferred way to declare an index is via the  
ActsAsFerret::define\_index method, in a file called config/aaf.rb.  
There you may declare several classes using the same index like this:

ActsAsFerret.define\_index(‘my\_index’,  
:models =\> {  
OneModel =\> {  
:fields =\> {  
:title =\> { :boost =\> 2 },  
:description =\> { }  
},  
:if =\> Proc.new { |r| r.published? }  
},  
AnotherModel =\> {  
:fields =\> {  
:title =\> { :boost =\> 2 },  
:another\_field =\> {},  
},  
:if =\> Proc.new { |r| r.should\_index? }  
}, :ferret =\> {  
:default\_field =\> %w( title description  
another\_field )  
})

No need to call acts\_as\_ferret inside your model anymore (though it  
will still work for the one index per class scenario).  
my\_index is the name of the index, to be used with ActsAsFerret::find:

ActsAsFerret::find(“some query”, ‘my\_index’)

to only search records of a given class, find\_with\_ferret works as  
expected:

OneModel.find\_with\_ferret(‘some query’)

Sorry for not documenting this stuff better…

cheers,  
Jens

Thanks for the update, Jens. Unfortunately, it looks like I’ll have to  
stick with the stable branch for now - these changes in trunk don’t  
jive well with my apps.

Thanks and keep up the great work!
