 I'm thinking something general, like NSTableView and it data source.
 In the search view, each criterion is in the format of "subject verb 
object",
 like ' (File Size) (is greater than) (142243) '.
 Data source provides the available "subjects" and user can choose them in 
a NSPopUpButton.
 The verb will change depending on the subjects type,
 which can be a NSString, NSNumber, NSDate, or other limited selection.
 User will input the object.
 All the criteria will be stored in the data source.
 Then the data source acts as a filter.
 Any application will supply a formated information to data source and
 this data source will return whether this information match the criteria.
 That's something I have in mind.

 Since Étoilé will have a search GUI and search engine,
 make them as some general classes will benefit other applications,
 like people subclass NSTableView instead of making a new one.
