A champion list, also called top doc or fancy list is a precomputed list sometimes used with the vector space model to avoid computing relevancy rankings for all documents each time a document collection is queried.
The champion list contains a set of n documents with the highest weights for the given term.
The number n can be chosen to be different for each term and is often higher for rarer terms.
The weights can be calculated by for example tf-idf.
