Indexing with xindy \index{Alf|see {Alfred}}

Question

When I use \index{Alf|see {Alfred}} I get the warning :

unknown cross-reference-class `see '! (ignored)

I dont want to use seealso;

Answer 1

You have to note that xindy does search for its keywords and a group, meaning that it wants something like see{Quack} or seealso{Quack}. The faulty piece is the space in your code. You should use \index{Alf|see{Alfred}} instead.
