Introduction

The Portuguese Web Archive provides an interface for users and tools to easily query the system. The response is a XML-based file (RSS 2.0).

Details

The PWA interface follows the OpenSearch 1.1 (Draft 5) namespace defined at http://www.opensearch.org/Specifications/OpenSearch/1.1/Draft_5.

It also follows the OpenSearch Time extension (Draft 1) namespace at http://www.opensearch.org/Specifications/OpenSearch/Extensions/Time/1.0/Draft_1 that describes how to set temporal search parameters.

The OpenSearch Description Document at http://arquivo.pt/opensearch.jsp describes the public interface and how the search client should make search requests.

Query

Parameters:

query={search terms} : query terms URL-encoded. (required)
