See zypp/PoolQuery_test.cc for how to set up various queries. Once set
up, you just iterate using selectable{Begin,End}(). Typically you do:


PoolQuery q;
q.addString("zypper");
q.addAttribute(sat::SolvAttr::name);
if (search_in_descriptions)
{
  q.addAttribute(sat::SolvAttr::summary);
  q.addAttribute(sat::SolvAttr::description);
}
if (use_globs)
  q.setMatchGlob();

// etc....

for (PoolQuery::Selectable_iterator it = q.selectableBegin();
       it != q.selectableEnd(); ++it)
{
  Selectable::Ptr s = *it;
}

q.begin() q.end() returns solvables; the SolvIterMixin makes also
q.poolItem{Begin,End} available IIRC.


If you'll need some convenience methods, or the perfomance is bad or
what, just tell me. Just bear in mind it currently returns one
selectable for each solvable, this needs to be fixed yet.

CCing zypp-devel just in case someone finds the info useful.
