Abstract
This paper discusses the proper treatment of multiple indexing fields, representations, or streams, in document retrieval. Previous experiments by Robertson and his colleagues have shown that, with a widely used type of term weighting and fields that share keys, document scores should be computed using term frequencies over fields rather than by combining field scores. Here I examine a wide range of document and query indexing situations, and consider their implications for this approach to document scoring.
