    Add your string to a Set, then pass that object as a parameter:
    Set<String> set = new HashSet<String>();
    set.add(myString);
    Searcher.searchAnd(set);

    It worked just fine!
    Just one remark: Searcher.searchAnd(set) should be inside a try/catch clause.

    Thank you for the help!
