Solr Suggester - How do I filter autocomplete results

[Mysurf Mail]

I want to filter the auto complete results from my suggester Lets say I
have a book table

Table (Id Guid, BookName String, BookOwner id)

I want each user to get a list to autocomplete from its own books.

I want to add something like the

http://.../solr/vault/suggest?q=c&fq=BookOwner:3

This doesnt work. What other ways do I have to implement it?
