Ferret talk - Dec 2007 - Does sort work for strings work?

Hi,

I am trying to get sorting working.  I have had success with numbers  
but when I try to sort my string fields nothing happens.  I am using  
the following code:

options = {}
s = Search::SortField.new(''object_title'', :reverse =>
false)
options[:sort] = s
@index.search_each("my query",options) do |id, score|
       puts "-->Document #{id} found with a score of #{score}"
       p @index[id].load
end

output:

-->Document 0 found with a score of 0.0534844100475311
{:date=>"2004-01-01", :object_title=>"This is the first  
title", :title=>"1", :page=>"1",
:object_content=>"This is the first
content"}
-->Document 1 found with a score of 0.0534844100475311
{:date=>"2005-01-01", :object_title=>"This is the second  
title", :title=>"2", :page=>"1",
:object_content=>"This is the second
content"}
-->Document 2 found with a score of 0.0534844100475311
{:date=>"2006-01-01", :object_title=>"This is the third  
title", :title=>"3", :page=>"1",
:object_content=>"This is the third
content"}
-->Document 3 found with a score of 0.0534844100475311
{:date=>"2007-01-01", :object_title=>"This is the fourth  
title", :title=>"4", :page=>"1",
:object_content=>"This is the fourth
content"}
-->Document 4 found with a score of 0.0534844100475311
{:date=>"2008-01-01", :object_title=>"This is the fifth  
title", :title=>"5", :page=>"1",
:object_content=>"This is the fifth
content"}

Notice it is not sorted by object_title!  Any help would be greatly  
appreciated.
