In this paper, we propose a new search method Fuwatto Search that allows users to retrieve documents in a document-by-document manner via a Web API. We present an implementation of the proposed method (i.e., Fuwatto CiNii Search), which targets the CiNii Article database, one of the largest academic article databases in Japan. The experimental evaluation of Fuwatto CiNii Search with newspaper articles demonstrates the retrieval effectiveness of 0.25 for precision at 10 and 0.17 for mean average precision.
