You are right Apache POI has the worst kind of documentation or you can say no documentation at all. So there is nothing much you can find except a few blogs.

Replace your for loop with:

for (String value : content.split("@")) {
            XWPFParagraph para = doc.createParagraph();
            para.setVerticalAlignment(TextAlignment.CENTER);
            para.setNumID(addListStyle(abstractNum, doc, numbering));
            if (value.contains("Second")) {
                para.getCTP().getPPr().getNumPr().addNewIlvl().setVal(BigInteger.valueOf(1));
            }
            XWPFRun run = para.createRun();
            run.setText(value);
        }

Create a multi hierarchy bullited list in MS-Word .docx manually and inspect its XML structure by renaming its extension to .zip, inside this zip you'll find word/document.xml, by inspecting it you'll find that its <w:ilvl w:val="0"/>, "ilvl" Indent Level that is responsible for you indentation so using above code you can create you multi level lists.

Here is how you set indent level:

para.getCTP().getPPr().getNumPr().addNewIlvl().setVal(BigInteger.valueOf(1));

Just increase indent level by BigInteger.valueOf((int)IndentLevel)
