Interface AusbildungSearchParams

Training type: one numeric bildungsart.id, e.g. 102 Berufsausbildung (trainingTypeProblem). A non-numeric value gets HTTP 400; an unknown number an empty result.

Education-voucher filter.

Start-date code(s), not a date: 2 = earlier dates, 101..112 = January..December of the following year (upstream OpenAPI); 0 and 1 are accepted and filter too (each kept about half of one live search's offers), with an undocumented meaning. Comma-separated for several (START_CODES).

Occupation id(s): the numeric dkzId from angebot.systematiken[], comma-separated for several (idsProblem; each item is trimmed, normalizeIds). A non-numeric id or an empty item (a trailing comma) is rejected: the API answers it with HTTP 400.

Location as Name_lon_lat (longitude first, -180..180; latitude -90..90), e.g. Köln_6.957_50.938 (checked by placeProblem); several places comma-separated are searched together, each checked. Only restricts the search together with a radius uk, so it is rejected without one (placeAndRadiusProblem).

0-based page; (page + 1) × size must be at most MAX_RESULT_WINDOW (10000).

Bundesland code from REGION_CODES (BAW, BAY, … THÜ), comma-separated for several. Each code is trimmed, NFC-normalised and uppercased before it is sent (normalizeRegions).

Page size, 1..MAX_PAGE_SIZE (20): the server clamps anything above 20 to 20.

Offer type, an integer 0..3 (STY_MIN..STY_MAX; the API rejects 4 with HTTP 400).

"sw" — search keyword. Currently ignored by the API; filter by occupation with ids.

Radius from RADII: "Bundesweit" (in any case, normalizeRadius) or 10, 25, 50, 100 (km); other values get HTTP 400. A km radius is ignored by the API without a place orte, so it is rejected without one.
