Where is the documentation for the syntax used in the

where

object below?

homesInPriceRange: async (parent, args, ctx: Context, info) => {
    const where = {
      AND: [
        { pricing: { perNight_gte: args.min } },
        { pricing: { perNight_lte: args.max } },
      ],
    }
    return ctx.db.query.places({ where }, info)
  },

and the gql

aggregate

thingie below:

numRatings: {
    fragment: `fragment NumRatings on Place { id }`,
    resolve: async ({ id }, args, ctx: Context, info) => {
      const reviews = await ctx.db.query.reviewsConnection(
        { where: { place: { id } } },
        gql`{ aggregate { count } }`,
      )
      return reviews.aggregate.count
    },
  },

I have been looking for some kind of reference on when you can use

filter

or that you can use

min

and

max

on an Int? Is google no longer serving me or is the documentation on this stuff sparse?
