We’re overhauling Dgraph’s docs to make them clearer and more approachable. If you notice any issues during this transition or have suggestions, please let us know.

While editing your schema, you might find it useful to include this GraphQL schema fragment. It sets up the definitions of the directives, etc. (like @search) that you’ll use in your schema. If your editor is GraphQL aware, it may give you errors if you don’t have this available and context sensitive help if you do.

Don’t include it in your input schema to Dgraph - use your editing environment to set it up as an import. The details depend on your setup.

The Int64 scalar type represents a signed 64bit numeric nonfractional value.
Int64 can represent values in range [-(2^63),(2^63 - 1)].

"""
The DateTime scalar type represents date and time as a string in RFC3339 format.
For example: "1985-04-12T23:20:50.52Z" represents 20 minutes and 50.52 seconds after the 23rd hour of April 12th, 1985 in UTC.
