Hi,
I have i am trying to add a search feature to a ruby on rails blog, so
ive decided to use ferret. So far i have had quite a few problems with
it, from following a few tutorials i didnt really understand... i am at
the point where i can make a search and it returns the score of the
result. I want it to also show the title of the post and i think i have
implemented it correctly but it doesn't.
This is the code in my search.rhtml:
<% @results.each_with_index do |result, index| %>
<%= result[:title] %>
Score: <%= result[:score] %><br/><br/>
<% end %>
And this is the controller:
def search
@query = params[:q]
@total, @results = Post.find_storage_by_contents(@query, :page =>
(params[:page]||1))
@pages = pages_for(@total)
end
This is the code from post.rb:
def self.find_storage_by_contents(query, options = {})
# Get the index that acts_as_ferret created for us
index = self.aaf_index.ferret_index
results = []
# search_each is the core search function from Ferret, which
Acts_as_ferret hides
total_hits = index.search_each(query, options) do |doc, score|
result = {}
# Store each field in a hash which we can reference in our views
result[:title] = index[doc][:title]
# We can even put the score in the hash, nice!
result[:score] = score
results.push result
end
return block_given? ? total_hits : [total_hits, results]
end
there is probably something i have missed before this is able to work,
if u have any ideas please help! thanks, Will
