Split function to split a string by a regex?

I want to implement a search UDF and I need to do the equivalent of myStr.split(' ').map(part => {}) in that UDF

There is a community npm package with a bunch of utility FQL snippets and UDFs. It has a StringSplit function that you might check out.

github.com

shiftx/faunadb-fql-lib/blob/master/src/functions/StringSplit.ts

import { query as q, ExprVal, ExprArg } from "faunadb"

export const StringSplit = (string: ExprArg, delimiter = "."): ExprVal =>
    q.If(
        q.Not(q.IsString(string)),
        q.Abort("SplitString only accept strings"),
        q.Map(
            q.FindStrRegex(string, q.Concat(["[^\\", delimiter, "]+"])),
            q.Lambda("res", q.Select(["data"], q.Var("res")))
        )
    )
