Thanks, Jens. Good catch; this little example works correctly after
fixing that change.
However, my ActsAsFerret index merging does _not_ work, and I'm
wondering if it's something to do with AAF's handling of documents in
an index?
Let's call my indexed class Company...
Company.find_by_contents('*')
=> #<ActsAsFerret::SearchResults:0x2b1699108878 @current_page=nil,
@total_hits=3, @results=[], @total_pages=1, @per_page=3>
yet on each partial index prior to merging, that query would return a
bunch of results as one would expect.
now, here's how I've built that index... any idea why the merged index
is broken?
module FerretHelpers
def merge_ferret_index_partitions(model)
model_dir = File.basename(model.aaf_configuration[:ferret][:path])
final_index_path = "/tmp/merged_parallel_ferret_index/#{model_dir}"
partial_index_path = "/tmp/partial_indices/#{model_dir}"
paths = Dir.glob("#{partial_index_path}/*")
paths.each do |path|
i = Ferret::I.new(:path => path, :create => true)
name = path.split('/').last
i << {:name => name}
i.close
end
readers = []
paths.each {|path| readers << IndexReader.new(path) }
index_writer = IndexWriter.new(:path => final_index_path)
index_writer.add_readers(readers)
index_writer.close()
readers.each {|reader| reader.close()}
index = Ferret::Index::Index.new(:path => final_index_path)
index.optimize
index.close
end
end
