get_all_records

• Combines functions of get_ddc_records and
  get_non_ddc records
• Retrieves DDC numbers and captions relating to a
  term AND retrieves terms mapped to retrieved DDC
  numbers from other schemes.
• Accepts a subject term
• 2 stage process
• First retrieves ddc_records with mappings
  denoting IDs
• Then, on selecting get related concepts, IDs
  are supplemented with corresponding terms from
  satellite schemes (the next slide shows the
  latter part of this result)

get_filtered_set

• Allows specified fields from specific
  terminologies or combinations of terminologies to
  be searched.
• Additional parameters can be selected e.g. NPT,
  RT
• Accepts a subject term

(Partial) result for pottery searching AAT
using get_filtered_set. Pref labels for BTs and
NTs can be retrieved by clicking get related
concepts when entering search term. ltzsrecordgt
