Hi Alexander,
Given that RDF-stores use SPARQL as their query mechanism, any form of
semantic search is going to use SPARQL ultimately to access to the triples.
Have you actually looked at the Virtuoso Facet Browser UI, like the one
available fro DBpedia at:
http://dbpedia.org/fct
To see they type of searches that can be performed ? If this is does not
provide necessary sophistication sought then via the Web Service API you should
be able to extend or develop your own semantic search engine.
OntoWiki which supports Virtuoso is classified as a Semantic Search engine at:
http://swuiwiki.webscience.org/index.php/Semantic_Search_Survey#OntoWiki
Details on configuring OntoWiki for use with Virtuoso is available from:
