HuriSearch is a specialized search engine that covers over 5,000 human rights websites, including international governmental organizations (e.g., UNICEF), nongovernmental organizations (e.g., Amnesty International), academic centers (e.g., Duke Human Rights Center), and National Human Rights Institutions (e.g., Irish Human Rights Commission).
Advanced search lets you restrict by country, issuing organization, and type of document (e.g., HTML or PDF).
You can also run a search and then filter.
For instance, when I searched for "reproductive health" and Indonesia, I found 96 documents—91 from NGOs, 5 from IGOs; 69 in HTML, 23 in PDF, and 4 in Microsoft Word. The source organization with the most documents was Indonesia's NGO Coalition for International Human Rights Advocacy (HRWG) (70).
