hi;
i have a KB in jess format ,each fact is definate like that :
(MAIN::triple
(predicate
"http://www.owl-ontologies.com/unnamed.owl#CODE_PARENT_GEOGRAPHIQUE";)
(subject "http://www.owl-ontologies.com/unnamed.owl#_30M_Instance_70";)
(object "30M"))
Here, the object slot contains a double-quoted Jess string -- an
RU.STRING.
QueryResult result1 = engine.runQueryStar("search-by-systeme", new
ValueVector().add("30M"));
That "add" method is going to add a Jess symbol -- an RU.SYMBOL, which
is written with no quotes. They are two different data types. Since
your facts contain RU.STRING, you must ensure that your query asks for
RU,STRING:.
QueryResult result1 =
engine.runQueryStar("search-by-systeme", new
ValueVector().add(new Value("30M", RU.STRING)));
