The snipped out portion is just where you process the results. In my
case, I am searching for gifts so here is how I search and collect the
Gift objects:
num = INDEX.search_each(query, {:num_docs => options[:limit],
:first_doc => options[:offset]}) do |doc, score|
logger.debug("Found doc: #{doc}, id: #{INDEX[doc]['id']}, score:
#{score}")
gifts << Gift.find(INDEX[doc]['id'])
end
Also, the reason I defined my own search method as opposed to using
find_by_contents is because I am not using the acts_as_ferret plugin.
>From looking at the acts_as_ferret code, it looks like you can just
use the SearchResults object returned by the find_by_contents since it
also includes the total hits needed to create the Paginator pages.
