Is there a standard control for developers to get the search field behavior like in Mail (Mac OS X 10.7) to make advanced searches with tokens?
In Mail the tokens are used to visualize a search for a mail which for example was sent by a person with the name "Steve Jobs". I try to accomplish the same but in another context.
What your looking for is called a token field. See the Token Field Programming Guide. (Also documented on the CocoaDev Wiki)
