Kingsley,
Here is the FCT query, and the SPARQL query in Virtuoso. The results there are valid. Here is the query on the live PoC. Here is the SPARQL text from Virtuoso:
select ?s1 as ?c1, ( bif:search_excerpt ( bif:vector ( 'Person' ) , ?o1 ) ) as ?c2, ?sc, ?rank, ?g where
{
{
{
select ?s1, ( ?sc * 3e-1 ) as ?sc, ?o1, ( sql:rnk_scale ( <LONG::IRI_RANK> ( ?s1 ) ) ) as ?rank, ?g where
{
quad map virtrdf:DefaultQuadMap
{
graph ?g
{
?s1 ?s1textp ?o1 .
?o1 bif:contains '"Person"' option ( score ?sc ) .
}
}
?s1 a <http://www.w3.org/2002/07/owl#Class> .
filter ( ?s1 = <http://xmlns.com/foaf/0.1/Person> ) .
}
order by desc ( ?sc * 3e-1 + sql:rnk_scale ( <LONG::IRI_RANK> ( ?s1 ) ) ) limit 20 offset 0
}
}
}
And here is the SPARQL text received from FCT by the live PoC:

Ignoring the malformed xml (which I think it implying the problem, i.e. the filter is not being included/applied to the query), the two SPARQL queries are not equal in syntax. But the criteria are the same for both, e.g. search all fields for text 'Person', rdf:type == owl:Class, and subject IRI == foaf:Person.
