ABSTRACT:
Disclosed is a technique for indexing data. For each token in a set of documents, a sort key is generated that includes a document identifier that indicates whether a section of a document associated with the sort key is an anchor text section or a context section, wherein the anchor text section and the context text section have a same document identifier; it is determined whether a data field associated with the token is a fixed width; when the data field is a fixed width, the token is designated as one for which fixed width sort is to be performed; and, when the data field is a variable length, the token is designated as one for which a variable width sort is to be performed. The fixed width sort and the variable width sort are performed. For each document, the sort keys are used to bring together the anchor text section and the context section of that document.
