Is it possible to filter kontent results (delivery api) by linked item type

Question

Is it possible to filter and only bring back content items what have a linked-item of type x eg

I have 3 content type A, B, and C

A has a field called subItems which takes either content type A, B or C

How would i construct a query for content-items that have at least one subItem of Content-type B

Answer 1

I think the scenario is not covered right in filtering operators .

On the other hand, you could filter out content items with [any] filter if you have their codename.

1. Load codenames of Content-type B
2. Use [any] operator for subitems element with loaded codenames

You could load codenames of Content-type B items using /items endpoint.

To prevent loading data you don't need (in that case you want to ignore all elements , you just need codename) you could use projection feature .

If you have more than 2000 content items (or hitting response size any other way) of type B, use /items-feed and load items page by page.

And then use [any] filter:
