Is there a way to write a groq query that checks if a boolean is true, and if so, returns an array of referenced documents? (example use case, on a homepage, I want to allow the client to enable/disable showing the 3 most recent blog posts)I have this, but it doesn’t work

{ features[_type match 'blogEntries'] { 'posts' : *[_type == 'post'][0..2] { ... } } }

I think I got it
  "posts": *[_type == 'post' && 'blogEntries' in (^.features[]._type)][0..2],

I guess the question now is, can I modify the limit based on a field value. Ie, inside of ‘blogEntries’ if I set the query to return 5 instead of three, can I make that range at the end become [0..4] ?

If you pass the end number as a parameter, you could replace
with something like

Could $num somehow be referenced from the query response
Feb 1, 2021, 6:35 PM
Yes, $num would be a query parameter that you could pass through the URI, as props, or even pulling from a document containing the ranges.

Here’s an example:

export async function getAllStaff(num) {
  const result = await client.fetch(
    `*[_type == "staff"] | order(firstName asc, lastName asc) {

  return result;
Then I’m calling the function from getStaticProps and passing in `num`:

export async function getStaticProps() {
  const allStaff = await getAllStaff(8);

  return {
    props: { allStaff },
    revalidate: 120,
