Is it a way to create a NSPredicate which checks not only one keyword match, but more keywords?
I know "CONTAINS[cd] %@", var operation which allow to filter like this:
string: "aaa bbb ccc ddd", keyword: "aaa" -> this will match, 
but how to filter this:
string: "aaa bbb ccc ddd", keywords: "aaa ccc"
                        
You probably need
|or operator.Something like
aaa|ccc
