Ferret talk - May 2008 - Searcher Explain

Hi,

I am unable to use the Searcher''s explain method.  Anytime I call it, I
get
Segmentation Faults and it kills the process I have running my Rails site.
Has anyone else had this problem?  Here is some code I am trying to use it
in...

search = Search.create(:query => query)

@quotations = []

searcher = Ferret::Search::Searcher.new("index")  #
FerretConfig::INDEX

bq = self.build_query(query)  # Builds a Boolean Query

searcher.search_each(bq) {|doc, score|
  @quotations << SearchResult.new(searcher[doc][:id],
searcher[doc][:quotation], searcher[doc][:author], score)
}

p searcher.explain(bq, @quotations[0].id).to_s

searcher.close




Thanks in advance for any help!

If I get this right, @quotations[0].id will give the value of the id
field of that result, which is not a valid argument to explain. What the
explain method expects instead is the ferret-internal document id (the
doc value in your search_each block).

cheers,
Jens
