Re: [O] how do I search state change dates?

This looks promising. However, the example at the link you referenced
seems to have its state changes inside a LOGBOOK property drawer. My
state changes are not inside a drawer. See excerpt below.  To change the
state, say from TODO to READING, I use C-c C-t and then can choose one
of my pre-specified states.  Should I put my state changes in a LOGBOOK
drawer? If so, how does that work?

** DONE Responsible Men          :fiction:BUlibrary:
   - State "DONE"       from "READING"    [2018-11-18 Sun 23:17]
   - State "READING"    from "TODO"       [2018-11-04 Sun 23:17]
