Here is another place where it's not quite working right.

When editing a query from the query edit page, any conditions
created by the expression editor are lost.

E.G. create a keyword search "keyword1 and not keyword2".
Save the search. You can execute the search and it will work fine.
Now edit the search and set the owner to semothing.

Note that the edit screen doesn't display

  "keyword1 and not keyword2"

anymore. If you save the query, you loose the keyword expression
even though it was not edited.

I am not sure if this is an issue with the underlying mechanism
we use to store the query or just a problem with the form that is created.
