My model's full_text_search method looks like:
def self.full_text_search(q, options = {})
return nil if q.nil? or q.empty?
default_options = {:limit => 10, :page => 1}
default_options.update options
# get the offset based on the page and limit
default_options[:page] = 1 if default_options[:page] == 0
default_options[:offset] = default_options[:limit] *
(default_options.delete(:page).to_i-1)
# now do the query with options
results = Article.find_by_contents(q, default_options)
return [results.total_hits, results]
end
My search controller uses it like this:
# build sort
@sf_published_at = Ferret::Search::SortField.new(:published_at_string,
:type => :string, :reverse => true)
@sort = Ferret::Search::Sort.new(@sf_published_at)
# set options
@options = {:limit => 20, :sort => @sort}
@total, @articles = Article.full_text_search(@query_string, @options)
And yes, you're absolutely right about sending in :limit => :all. I
forgot to mention that in my earlier post.
I'm currently getting around this issue by returning all the results and
sorting in ruby.
Thanks for looking into this.
