Abstract
Methods and systems for the generation of computer readable indexes or other ordered lists are provided. A corpus of electronic documents or other electronic information is parsed into postings that include key and reference pairs. An inversion buffer in memory is explicitly or implicitly formatted to receive the postings in a predetermined order by key. Each key is assigned a space in the inversion buffer that is subsequently filled with references associated with the key during an inversion method. In an embodiment, an index file is generated directly from the inversion buffer, or in the case of large inversions, from a plurality of inversion buffer segments.
