Desktop search hackfest 1st day

First proper day of desktop search hackfest behind. We had good progress on the most important areas already and we are making now similar progress on the second day. The biggest one was that we agreed on the ontology changes that have been raised with variable solution candidates now for a year. The solution is clean and simple. It is future oriented by allowing proper object relations in the ontology, but still retaining the possibility to be efficient on the cases where you are only interested in a lablel-like property of the relationship rather than the actual object in the relation.

Today we have also been able to extend the query api to reflect this ontological change. We also agreed to add proper support of nested queries that truly makes the search api powerful. Biggest issues remaining currently are in the area of live queries. Here is a very good example of a real world ;) use case. By the way, using Gobby (gnome application) makes document collaboration astonishingly easy.

Maybe we could try to draft a spec as well? Maybe just some notes?
Because it's still not really clear what everyone up to because everyone is up to slightly different things.

  Match all documents with keyword "biology" which author comes from the
  same country as any person with name Jim.
