OptionalfieldsClient-side field projection: keep only these value fields. Needs at least one non-blank name; blank entries next to real names are dropped.
Indicator code (AI002-1-5) or table form (ai002_1_5); resolved against the catalogue.
OptionallevelGeo level: a friendly name (land, kreis, …) resolved to a typ. Defaults to
DEFAULT_LEVEL (land) when omitted (undefined or null).
OptionalregionClient-side region filter (not blank): an AGS (numeric; leading zeros ignored, and a
key padded with zeros, such as the official 8-digit key of a kreisfreie Stadt,
matches the shorter key the level carries), or a name — rows whose whole name
equals it when there are any, else every row whose name contains it. See
matchRegion, and QueryResult.region for how it matched.
OptionalyearYear; defaults to the indicator's newest catalogue year. The data host may not have loaded that year yet, in which case the query returns no rows.
