Experimental research
The Cranfield Studies were conducted by Cyril W. Cleverdon at the College of Aeronautics, Cranfield, UK – Cranfield I (1957–1962) and Cranfield II (1963–1966).
They were controlled experiments: test collections of documents, sets of queries and relevance judgements were used to compare indexing languages (UDC, alphabetical subject headings, faceted classification, Uniterm) under controlled conditions, measuring performance with recall and precision.
This test-collection model of laboratory experimentation became the foundation of information retrieval evaluation, later carried forward by SMART and TREC. They were not case studies, historical studies or surveys.
Hence, the answer is Experimental research.
