Martin Michlmayr:
Martin mentioned on the list recently:
> one can just use a SQL command, something like SELECT location WHERE
> date >= 2019-02-01 and flag ='!' and iterate using "next-error" in
> Emacs. Perhaps that should be documented better.
Zack said it's not mentioned in the BQL documentation.
