How to use REX in a search called via REST API?

In my first post,

I need to search Splunk using the REST API. How do I get the system to actually return me some results?

Steps

POST a search, example:

search=search index=myIndex earliest=-1d "[nice-keyword]" AND "Nice catch-phrase" | rex field=_raw "reportingSystem\":\s+\"(?<system>\d{3})[\s\S]+operationCode\":\s+\"(?<opcode>\w+)[\s\S]+ticketId\":\s+\"(?<ticket>\d*)[\s\S]+transactionCode\":\s+\"(?<txcode>\w+)[\s\S]+NumericCode\":\s+\"(?<agency>\d*)" | table system, opcode, txcode, agency

In the SEARCH User Interface, this makes a nice report
Grab the job search ID.
Continually GET the job status of the POSTed search until DONE or something else that helps me stop polling.
Ask for the job results. Get 200 OK but no content.

How does one actually format a search that can provide actual results via the API?

Stumped. For days. I'm using Postman before moving on to my favorite middleware tool.

Thank you.

Having found that url encoding works well (thanks to other posters), I have made some progress! Next to work out how to find the eventId and to be able to do a JOIN in the same search via API.
