Notes disappear with blank search term

Here is the current config.cson:

"*":
  core:
    db:
      backupPath: "/home/davem/backups/inkdrop"
      machineId: "jyVxcX6vk"
    lastNavigationState:
      editingNoteId: "note:FPsJaRRub"
      queryContext:
        mode: "search"
        searchKeyword: "docker"
      sidebar:
        workspace:
          bookId: ""
          visible: false
    mainWindow:
      fullscreen: false
      maximized: false
      noteListBar:
        w: 272
      position:
        x: 382
        y: 170
      sideBar:
        collapsedBooks: [
          "book:T0WxWyOkJ"
          "book:fK18xLnmF"
          "book:1xPJeMPOH"
          "book:PzQO8zbWt"
        ]
        visible: false
        w: 170
      size:
        h: 957
        w: 1234
    themes: [
      "default-light-ui"
      "solarized-light-syntax"
      "colorfi-preview"
    ]
  editor:
    fontSize: 14
    styleActiveLine: true
    viewMode: "edit"

When the problem resolves, I will look for:

core.lastNavigationState .editingNoteId

and report back what I see.
Thanks for the link to the “hacking” page.
I have been meaning to make a few plugins at some point.
