Abstract
A method can include: reordering an enriched inverted index associated with a database, the enriched inverted index including a first inverted list having a first plurality of current document identifiers of records that contain a first data value, the enriched inverted index further including a first data structure storing enrichment data, the reordering of the enriched inverted index comprising: generating an ordinal sequence corresponding to an order of a first plurality of current document identifiers that include a change of at least one of the first plurality of current document identifiers to a new document identifier; determining a reordered ordinal sequence corresponding to a sorted order of the second plurality of document identifiers; separately reordering, based at least on the reordered ordinal sequence, the first plurality of current document identifiers in the first inverted list and the enrichment data in the first data structure.
