NSSearch Field Predicate Filter - objective-c

Question

-(void) searchFieldChanged{
MPVTModelList *list = [[MPVTModelList alloc] initWithClass:[MassPOAssignmentModel class]];
[intersectionTableView selectRowIndexes:[NSIndexSet indexSetWithIndex:1] byExtendingSelection:NO];
// [searchIntersectionField setStringValue:[[[searchIntersectionField stringValue] stringByReplacingOccurrencesOfString:#"\\" withString:kMPVTBlankString] stringByReplacingOccurrencesOfString:#"\'" withString:kMPVTBlankString]];
[searchIntersectionField setStringValue:[searchIntersectionField stringValue]];
NSArray *array=[[NSArray alloc]init];
if([[[searchIntersectionField cell]placeholderString] isEqualToString:#"Pricing Org"]){
NSArray *tempArray=[[[searchIntersectionField stringValue] uppercaseString] componentsSeparatedByString:#","];
NSLog(#"tempArray %#",tempArray);
NSString * str=[[searchIntersectionField stringValue] uppercaseString];
NSLog(#"str is %#",str);
for(id item in tempArray ){
[intersectionTableView reloadData];
array=[[[self intersectionList]entities]filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:#"mpoPricingOrg.stringValue contains[cd] %#",item]];
NSLog(#" item is %#",item);
NSLog(#"insie if arr %#",array);
[list appendEntities:array];
NSLog(#"hello %#",[[searchIntersectionField cell]placeholderString]);
}
}
else{
NSLog(#"inside else");
array = [[self searchFieldController] updatePredicateWithFilterText:[searchIntersectionField stringValue] searchArray:[[self intersectionList] entities] searchTableView:intersectionTableView];
NSLog(#"in side else array %#",array);
[list appendEntities:array];
}
[self setIntersectionList:list];
[list release];
[intersectionTableView reloadData];
[intersectionTableView deselectAll:nil];
[super updatePlacard:intersectionTableView];
}
I have called this method in -(void)controltextDidEditing. But when I enter "China" the filter predicate works fine. But when I enter "China,Brazil" it only shows the record for China and not for Brazil. Please suggest a better way of doing it.
