Hello
I have loaded DBpedia and Linkedmdb in Virtuoso and I have update the
indexes by running the commands:
DB.DBA.RDF_OBJ_FT_RULE_ADD (null, null, 'All');
DB.DBA.VT_INC_INDEX_DB_DBA_RDF_OBJ ();
First, for DBpedia, and it works perfectly. Then for Linkedmdb, but
it does not seem to work very well. For instance, the query
SELECT DISTINCT ?s ?o FROM <http://data.linkedmdb.org> WHERE {{?s
rdfs:label
?o .FILTER( bif:contains(?o, "angelina and jolie" ) )}}
gives many irrelevant results such as:

Any idea why? Is there anything else I should do? I run the commands
to create the indexes more than once (as the process was interrupted
first time I tried to create the indexes for linkedmdb), but it stills
the same.
Thanks!
Vanessa :)
