    }
    Operator op = (compareOp == TimelineCompareOp.NOT_EQUAL) ? Operator.AND : Operator.OR;
    TimelineFilterList list = new TimelineFilterList(op);
    String[] splits = expr.split(TimelineParseConstants.COMMA_DELIMITER);
    for (String split : splits) {
        list.addFilter(new TimelinePrefixFilter(compareOp, split.trim()));
