Abstract

We show that a full element-index can be as space-efficient as a direct index with Dewey ids, after compression using typical techniques.

Keywords

Space Complexity Query Processing Conjunctive Query Direct Index Ancestor Node 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
