[Xapian-discuss] xapian uses inverted index?

[oscaruser at programmer.net]

Folks,

Been looking the IR docs [http://www.xapian.org/docs/intro_ir.html], but didn't see anything about an inverted index. Is such a datastructure used by Xapian to help relevancy, improve search results or a method to determine context? e.g., "At a simple level a computerised IR system puts the terms in a direct access, or index file. A term can be looked up and its posting list found."

Thanks,
OSC
