How can I order a query by parent page attribute first and then by child page attribute? By title or by menu_order is acceptable.
For example, if my query matches child pages, and my search results page displays a list of parent titles with subpage titles...
Names - Joe Names - Reuben Names - Victor Sandwiches - Hamburger Sandwiches - Reuben
I want them sorted as above in alphabetical order of parent then of child, or by menu_order of parent then of child. If you want a reason, it's because some of my subpages have matching titles and need further categorization.
