Here, the object slot contains a double-quoted Jess string -- an
RU.STRING.

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)));
