I will start hacking on this again today, a plan to split it into two
parts.
1.) I will start with negation
2.) the next step is wildcards
There are still a few open question to me:
wrt 1.)
* for which fields do we allow negation?
- Subject.{Uri, Interpretation, Manifestation, Origin, Mimetype}
(Text is too expensive, and Storage make no sense as we have an Enum
for both cases)
- Event.{Interpretation, Manifestation, Actor}
(we do not allow searching by Id, we have different ways to query by
Timestamp)
wrt 2.)
* we will only allow wildcard searches like "sometext*"; and not "some*xt"
or "*text"
* Allowed fields for wildcard searches are:
- Subject.{Uri, Origin, Mimetype}
- Event.{Actor,}
(in both cases Manifestation/Interpretation are covered by
expansion feature, I think allowing wildcards is not necessary)
Any comments?

Bug description:
- How can I get all events except those with interpretation VISIT_EVENT?
- In case you give me above the awful answer "looking for all interpretations
except VISIT_EVENT", how can I get all events except those from application
"firefox.desktop"?
- How can I get all those events whose URI ends with "myfile.txt"?
- And those events whose title contains "zeitgeist"?
