Systems and methods for processing an index are described. A pulse in an inverted index refers to a group of items that do not occur in any other pulse in the index. When processing a query against an inverted index in which pulses are present, the query is processed against a single pulse. The end of the pulse is determined based on the characteristics of the pulse and the linked list nodes that comprise the postings lists from which the index was generated. In some embodiments, index updates are applied to the query result obtained from a single pulse to provide an efficient and up to date query result.
