Posting list

[fabric fabricio]

Can you explain how dictionary are linked with this implementation of
posting lists. In traditional case we have dictionary like
hashmap[String,List(int,int)] //word -> docid, termfreq. In this case
dictionary points to "parallel arrays" slots and in the "poitner array"
points to most recent docid in the posting list what means "to search the
posting list" in other words how this maps to List(int,int) part
