  e.g.)

$ cat index-dump.sdf
table_create —name Video —flags TABLE_HASH_KEY —key_type UInt32
table_create —name Tag —flags TABLE_HASH_KEY —key_type ShortText
column_create —table Video —name title —flags COLUMN_SCALAR —type ShortText

$ cd path/to/index/
$ ls Tag.index_tags
Baseball.dump  IT.dump       Server.dump  Sports.dump  groonga.dump
$ cat path/to/index/Tag.index_tags/groonga.dump

  record.value to get the original record.
  The following code shows how to use old style:
  result_since_2_1_0 = table.sort([“sort_key”])
  result_before_2_1_0 = result_since_2_1_0.collect do |record|
  record.value
