Xapian discuss - Oct 2008 - Open postlist

Hi,

The FAQ (http://trac.xapian.org/wiki/FAQ/UniqueIds) recommends,
to open a postlist instead of a search:
     If you want to retrieve the document, open the postlist for
"Q65A"
     and read the first (and only) document id (this will be a little more
     efficient that running a search for "Q65A").

How can I open the postlist?

Thank you very much
Markus

In C++, use Xapian::Database::postlist_begin("Q65A") (compare with
postlist_end("Q65A") in the usual way). In other languages (such as
Python) there may be more idiomatic approaches - see the bindings
documentation for your language in this case.
