How to use Dataview for notes that contain multiple values for a single field? (self.obsidianmd)

I have a number of individual notes for various books I've read, with a YAML field for "author." This works great with Dataview, except when there are multiple authors of a book. I assumed I could just add another YAML line "author: Sample Author" to add the second author, but then Dataview does not return results for either author.

Does anyone know how to change my query so it will return results for either author? Is this possible?

My current search is:

dataview TABLE without ID link(file.link, title) as "Title", author FROM #books Where author = "Sample Author"

I used this for my recipe notes:

ingredients:
- name     : Carrots
  quantity : 2
  units    : ""
  format   : grated
- name     : Curry Powder
  quantity : 1
  units    : tbsp
- name     : Onion
  quantity : 1
  format   : sliced

And then use FLATTEN ingredients to create a nicely formatted table of ingredients.

Ooo, nice tip! I’ve got a few recipes in my vault I’ll have to try this out on.
