Database Software

I'm applying a filter in a SEM_MATCH query using the orardf:textContains operator this way:

SELECT s, p, o
FROM TABLE(SEM_MATCH( '
SELECT ?s ?p ?o
WHERE
{ ?s ?p ?o
  FILTER (orardf:textContains(?o, "fuzzy(search_string_1, 70, 1)"))
}',
SEM_Models('model'),
NULL,
NULL,
NULL));

Now I would like to filter by more than one string and order results by number of keyword matched. Something like this:

SELECT s, p, o, scr
FROM TABLE(SEM_MATCH( '
SELECT ?s ?p ?o (score(1) as ?scr)
WHERE
{ ?s ?p ?o
  FILTER (orardf:textContains(?o, "fuzzy(search_string_1, 70, 1) ACCUM fuzzy(search_string_2, 70, 1)", 1)) 
}
ORDER BY ?scr',
SEM_Models('model'),
NULL,
NULL,
NULL));

I was hoping to use the optional third argument of orardf:textContains as a label to be referenced in the SCORE operator (such as in the CONTAINS operator of Oracle Text) but I couldn't figure out how to use it since the score function is not defined in that context.

Is there a way to achieve this?

Thank you
