Abstract
In one aspect, methods and systems for variable-block length encoding of data, such as an inverted index for a file are disclosed. These methods and systems provide for relatively fast encoding and decoding, while also providing for compact storage. Other aspects include a nearly 1:1 inverted index comprising a position vector and a data store, wherein values that have a unique location mapping are represented directly in the position vector, while for 1:n values (n>1), the position vector can include a pointer, and potentially some portion of information that would typically be stored in the data area, in order to fully use fixed width portions of the position vector (where a maximum pointer size is smaller than a maximum location identifier size).
