- Legislation articles: sourceTypes=article - Article-level records for targeted legal provision search.
- Court decisions: sourceTypes=court_decision - Judgments and case law with citations, dates, courts, and source links.
- Official documents: sourceTypes=official_document - Circulars, directives, reports, and other materials issued by public authorities.
- Literature: sourceTypes=literature - Books, journals, and other legal literature available to the authenticated user.

Omnilex also indexes circulars, directives, administrative materials, doctrine, commentary, and other legal documents where they are available in the legal source catalog.

The HTTP search endpoint does not require authentication for public sources. Literature is access-controlled, so anonymous requests do not return restricted publications. Responses contain legislation, courtDecisions, officialDocuments, and literature groups.
