The below is the code for search in Jtable or Model. tf_Search_12 is my Textfield.

    tf_Search_12.getDocument().addDocumentListener( new DocumentListener() {


                @Override public void insertUpdate(DocumentEvent e)
                {
                    Search(tf_Search_12.getText().toUpperCase());
                }

                @Override public void removeUpdate(DocumentEvent e)
                {
                    Search(tf_Search_12.getText().toUpperCase());

                }
                @Override public void changedUpdate(DocumentEvent e)
                {
                    Search(tf_Search_12.getText().toUpperCase());
                }
            public void Search(String s)
                {
final TableRowSorter<TableModel> Sorter1 = new TableRowSorter<>(Model);
                JTable table = new JTable(Model);
                table.setRowSorter(Sorter1);
                JTable_Scroll.setViewportView(table);
                table.setModel(Model);

                    String copyString = s;
                    copyString.toUpperCase();
                    if(copyString.length()==0) {
                        Sorter1.setRowFilter(null);
                        Sorter1.getModelRowCount();
                    }
                    else {
                        Sorter1.setRowFilter(RowFilter.regexFilter(copyString));
