I have a sample project that does filtering and searching exactly as
you describe at http://returnself.com/code.php. It is based on the
filtering array controller on mmalc's page at
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
Of course the "instant" part will depend on what your search routine is
doing.
hope that helps,

I'm trying to implement searching ala iTunes, Xcode API documentation,
etc, for my NSArrayController. I've subclassed it to override the
arrangeObjects: method to filter the array, and I'm trying to figure
out how to connect the search string to the array controller. I'm
getting really frustrated with the two outcomes...
1) I use target/action and implement a method in the array controller
subclass, and whenever I type a key into the search field, about
0.5sec later the search is reflected in my NSTableView
or
2) I use bindings to bind the value of the search field to the search
string in the array controller (the setSearchString method also calls
rearrangeObjects). This causes the NSTableView to update instantly (no
delay whatsoever) but also results in the search field resigning
firstResponder status after a single key stroke, so to enter multiple
keystrokes (ie a word) i have to keep clicking in it for each
character.
How can I have instantaneous updating of the NSTableView without this
silly firstResponder issue? Ie how can I make it behave just like
iTunes/Xcode
