Hi,

I noticed that App Search does not support nested object types ([Schema Design](https://swiftype.com/documentation/app-search/api/overview#schema-design)). What data model would you suggest in order to support the data model and query given below?

e.g. my data model is:

course (1) -- (\*) section

section properties:

- campus
- semester

I would like the query to return all courses containing a section offered in Summer 2019 (semester) at the Loyalist campus

Hi @omairkhawaja

Let's say the course Math 1 is offered in

- Summer 2019, Loyalist campus and
- Winter 2020, Bancroft campus

You could index this data as 2 documents

- (Math 1, Summer 2019, Loyalist campus)
- (Math 1, Winter 2020, Bancroft campus)

so the Schema becomes:

- all course properties (flattened)
- campus
- semester
