Input parameters:

- `in_force` (boolean): true = tylko obowiazujace akty. Pomin zeby objac wszystkie.
- `limit` (number): Maks liczba wynikow (1-50). Domyslnie 10.
- `publisher` (string): DU = Dziennik Ustaw (ustawy, rozporzadzenia), MP = Monitor Polski (uchwaly Sejmu, postanowienia Prezydenta, obwieszczenia).
- `title` (string): Fragment tytulu (po polsku, z odmiana - np. 'ochronie' znajdzie 'ustawa o ochronie...').
- `type` (string): Typ aktu (po polsku, dokladnie jak w bazie).
- `year` (number): Rok publikacji aktu.

### `get_act` (~132 tokens)

Pobiera szczegoly aktu po identyfikatorze ELI (np. 'DU/2018/1000' dla Ustawy o ochronie danych osobowych z 2018 r.). Zwraca pelne metadane: tytul, typ, status obowiazywania, wejscie w zycie, slowa kluczowe, linki do tekstu HTML/PDF i strony ISAP.

Input parameters:

- `eli` (string, required): Identyfikator ELI w formacie PUBLISHER/YEAR/POSITION, np. 'DU/2018/1000'.

UWAGA: dla aktu bazowego HTML to tekst OGLOSZONY (brzmienie pierwotne), nie stan obowiazujacy - `structuredContent.text_version` to rozroznia. Bledy: `text_unavailable_use_pdf` (akt ma tylko PDF), `not_found` (brak frazy albo aktu), `invalid_eli`.

Input parameters:

- `eli` (string, required): ELI aktu, np. 'DU/2018/1000'.
