hi all, So I have a ferret question. Suppose I have a bunch of documents I indexed using ferret. For the sake of simplicity, all my documents have basically 1 relevant field: "city", which I set up during indexing. So my question is: how do I get all the different values for 'city' ? (without having to go through every single document). There's got to be something that can tell me all the different cities used in all my document, like ['NY', 'SF', 'LA'] (assuming all my documents are either in LA, SF or NY) Thanks for your help -Didier ps: I know that I can already get the list of 'field names' using: reader = Index::IndexReader.open(<index dir>) p reader.get_field_names but I can't seem to find the missing link to get to the list of values for a given term...

I don't have time to test it but it should be pretty close. reader = Index::IndexReader.open(<index dir>) term_enum = reader.terms_from(Term.new("city", "")); cities =  while (term_enum.term.field == "city") cities << term_enum.term.text break if not term_enum.next? end Cheers, Dave
