  This paper presents an advanced search engine prototype for bibliography
retrieval developed within the CHRONIOUS European IP project of the seventh
Framework Program (FP7). This search engine is specifically targeted to
clinicians and healthcare practitioners searching for documents related to
Chronic Obstructive Pulmonary Disease (COPD) and Chronic Kidney Disease (CKD).
To this aim, the presented tool exploits two pathology-specific ontologies that
allow focused document indexing and retrieval. These ontologies have been
developed on the top of the Middle Layer Ontology for Clinical Care (MLOCC),
which provides a link with the Basic Formal Ontology, a foundational ontology
used in the Open Biological and Biomedical Ontologies (OBO) Foundry. In
addition link with the terms of the MeSH (Medical Subject Heading) thesaurus
has been provided to guarantee the coverage with the general certified medical
terms and multilingual capabilities.
