Also known as: category ID
The classification an indexer assigns each entry, drawn from a numeric scheme common across most sites: 2000 for movies, 5000 for television, 3000 for audio, 7000 for other, with sub-codes beneath each. Searches filter on these numbers rather than on text, so a miscategorized entry can be invisible to a query that asks for only one range.
