Abstract
In one example, documents that are examined by a search process may be scored in a manner that is specific to a domain. A domain may be a substantive area, such as medicine, sports, etc. Different scoring approaches that take aspects of the domain into account may be applied to the documents, thereby producing different scores than might have been produced by a simple comparison of the terms in the query with the terms in the documents. These domain-based approaches may take a query into account in scoring the documents, or may be query-independent. Each approach may be implemented by a scorer. The combined output of the scorers may be used to generate a score for each document. Documents then may be ranked based on the scores, and search results may be provided.
