Many files contain fields, such as Author or Title in PDF Document Properties.
Search Cloud One automatically detects fields in many file types to make them searchable.
You can optionally add additional fields directly via the Console.
You can search a Field by entering a search request such as: Author contains Shakespeare.
However, if you have created Filters using the Search Cloud One WordPress Search Plugin, the user can click the filter icon, enter Shakespeare, click Apply to carry out the same field search.
Legal Search demo shows Field searching with Filters created in the WordPress Search Plugin.
