• Filter
  
  • A Filter is a condition, which is applied to the data in the DAM Center during a search. 
• Group
  
  • A Group is a conditional collection of 1-many Filters, ie a set of if- and else-if statements.
• Draft - Comparison Type
  • Determines how a given Filter does its "filtering".
• Input Type
  • Determines how any Visible filter gets the user's input. This is specific to Media Manager and Video Portal, ie Input Type can be used to gather a search's parameters and therefore has no impact on the search itself.
• Visible filter
  
  • If a Filter is visible, then parameters for that filter can be supplied by the user in Media Manager and Video Portal.
• Predetermined values
  
  • If the parameters for a Filter are known in advance, predetermined values can be applied to the Filter. If Predetermined values are applied to a Filter, any parameters supplied by the user or client code will be ignored.

• ID
  
  • The ID has two different implications: one for Input, and one for Output
    • Input: The ID of a Filter is the name of the parameter given to the search.
    • Output: The ID of a Value Field is the name of the property in the JSON returned by the search. It can also the name of a label, which is used in Media Manager and Video Portal to display the output of a Value Field.
• Custom attributes
  • Custom attributes are user-defined attributes of a Filter or Value Field.
• Draft - Field
  
  • A Draft - Field is used in conjunction with a Meta data field to specify a value other than the default Meta data field value.
  Draft - Aggregate
  An Draft - Aggregate behaves exactly like an SQL aggregate function in that it performs a calculation on a set of values and returns a single number
• Meta field group
  
  • A meta data field belongs to a meta field group.

A user can add three different kinds of Filters and Value Fields:

...

"searchFields" → Group.

"valueHandler" → "Draft - Comparison Type". 

"renderType" → "Input Type".
