This paper has presented an integrated approach to indexing and querying fulltext and metadata information which is both intuitive for the user and e#cient to implement. It achieves this by building on top of a common full-text search engine and by only slightly modifying the usual Google-like search interface to allow the specification of RDF fragments as part of the query. Additionally, our approach provides inexact matching of user queries and ranking of results, evaluating metadata matches the same way as full-text matches, with the ability to return results even for incomplete and over-constrained metadata queries
