A computer identifies within a document multiple matching chunks in response to a search request from a user. The search request includes one or more search keywords and each of the multiple matching chunks matches at least one of the search keywords. The computer partitions the matching chunks into multiple groups. The matching chunks within a respective group have an associated matching level to the search request. The computer returns one or more groups of the matching chunks to the user in an order consistent with their respective matching levels to the search request.
