Field Aliases
Create combinations of fields to use in searching using Field Aliases. Perhaps you know that users would like to search by names that may appear in email author, recipient, cc and bcc fields. You can create a field alias, so that users can search all these fields in one simple query. Field Aliases are displayed at the top of the Field Name drop-down list in the Search Assist.
Click Add Field Alias to create a new alias. Then enter a name for the alias and click Submit.
It is important to consider what types of fields you are adding or combining to this alias. Are you making an alias for several date field, text or number fields? Do some of these fields have facets built upon them? You cannot create an alias that combines different field types, such as date and text fields. Make your selection at Field Type and then click Add Fields.
The list of fields you can add to this alias is determined by the Field Type you selected. Select the checkboxes to apply your desired fields (you can use the buttons to select or clear all) and then click Update:
The fields selected now appear at Selected Fields. You can remove one field by pointing to it and clicking the red X. You can also continue to add fields, remove all fields or edit the name of the alias.
