While we are at it - I think the solution should also be able to tackle
the case where we can support queries that does not match files that
have been deleted (until now we have been very focused on the case of
moved files). So I guess this would simply boil down to
subject_uri_current != ""?

Bug description:
An issue we are facing at the moment is that ppl lose track of there files in a 
timeline if the file was moved around or renamed. I would propose using 
taskview or patch nautilus to actually grab those events and either:
1) Modify the uris in the uris table
2) Create a new table with    | new_id | old_uri_id | event | to map uris to 
their actual ids and the event that allowed the change, this would allow us to 
track a history of renaming or moving a file. It will look a bit like the 
following:

9 | 9 | 48124  # CREATE EVENT
12 | 9 | 48126 # MOVE EVENT

In other words the last row means uri 12 was moved from uri 9 with event 48126

UPDATE:

3) Create a changable_uri table that is a map of the uri table. it gets updated 
upon moved and rename.
We then add new resulttype that allow you to ask for either pureSubject or 
adaptedSubject. depending on which one is chosen we then use the according 
table in the join of the find_events_query :)
