Hi,
I''m having some trouble with ferret search_each. I''m posting
rails''
script/console output, so I guess you can decrypt it:
>> res = []
=> []
>> index.search_each(''name: a*'') do |doc, score|
?> res << doc
>> end
=> 50
>> res.size
=> 10
>>
I''m guessing the ''=>50'' after search_each
indicates that there are 50 documents returned. How come I can only see 10 in
the array res?
Thanks much,
Vamsee.

How come I can only see 10 in the array res?If you look at Index::Index''s search_each method you''ll see it calls do_search internally, which in turn calls Search::IndexSearcher''s search method. This search method takes an options hash which accepts the following keys: # filter:: filters docs from the search result # first_doc:: The index in the results of the first doc retrieved. # Default is 0 # num_docs:: The number of results returned. Default is 10 # sort:: An array of SortFields describing how to sort the results. So it is returning 10 docs due to the fact that num_docs defaults to 10. I''ve been waiting for David to return to bring this up again, but I think this code should be moved out of Search::IndexSearcher into Index::Index and that there should be a Hits class a la Java Lucene to manage the hits returned. -F
