Configure the columns and values displayed in views
By editing the display.xml file, you can define which columns are available in views and how they are displayed. By editing the Index Definition document, you can control the display of values in views.
You can define a column as a <key> element
                inside the <columns> section in the
                display.xml file. Each <key> contains attributes that define the
               	 heading, index name, alignment, sort order, sort type, type of information,
              		visibility, and column width for the column. You must define the index in the
                    Index Definition document with the
                	attribute KEEPEXTRACTEDVALUES="True" and with a
                    <field> element in the <summaries> section.
