The data structure at the core of large-scale search engines is the inverted index, which is
essentially a collection of sorted integer sequences called inverted lists. Because of the …

In many important applications—such as search engines and relational database systems—
data are stored in the form of arrays of integers. Encoding and, most importantly, decoding of …
