Abstract

Large inverted indices are by now common in the construction of web-scale search engines. For faster access, inverted indices are indexed internally so that it is possible to skip quickly over unnecessary documents. To this purpose, we describe how to embed efficiently a compressed perfect skip list in an inverted list.
