Use the search command with the publikujici filter set to the municipality name, such as "Statutární město Brno". All words in the name must match, and you can combine it with legal area or document type filters to narrow results.

Use the druhPredpisu filter with exact Czech values like "Obecně závazná vyhláška" for ordinances or "Nařízení" for regulations. Values require correct Czech diacritics, as ASCII-stripped variants return zero results.

All documents come from a single official source: Sbírka právních předpisů (CZSB) at sbirkapp.gov.cz. The collection contains approximately 76,000 legal regulations and 130 other acts including Constitutional Court rulings.

Yes, use the platnost filter for validity status (e.g., "Platné" for valid acts) and date range filters for issue, publication, and effectiveness dates in YYYY-MM-DD format. Cancellation dates are document-specific and not usable as filters.

Zero results usually occur when Czech diacritics are stripped from filter values like document type or legal area. Ensure exact Czech spelling with diacritics, and verify the publisher name matches the official municipality designation.
