Hi!
Why do you try doing this the hard way?
There's really no reason to use Ferret directly for a blog search
once you have acts_as_ferret in your Rails app. Here's the simplest
possible example:
Model:
class Post
acts_as_ferret :fields => { :title => {}, :content => {} }
end
Controller:
def search
@results = Post.find_by_contents(query)
end
View:
<ul>
<% @results.each do |result| %>
<li><%= result.title %><br />
Score: <%= result.ferret_score %>
</li>
<% end %>
</ul>
For implementing paging across your result set, please check out

Regarding your initial problem with missing titles - acts_as_ferret by
default stores no attributes but the id of your records in the ferret
index, to keep index size small. To get around this specify :store =>
:yes in the field options for your title field:
acts_as_ferret :fields => { :title => { :store => :yes }, :content => {} }
However as I said above, just go the easy way...
