Missing redirects from Wikipedia API

Question

I'm trying to get redirects for a Wikipedia page by mean of this query:

https://en.wikipedia.org/w/api.php?action=query&generator=search&format=json&gsrsearch=iiroc&gsrlimit=10&prop=pageprops|description|redirects&redirects

As you can see, the page "Investment Industry Regulatory Organization of Canada" gets no redirects:

            "18847030": {
                "pageid": 18847030,
                "ns": 0,
                "title": "Investment Industry Regulatory Organization of Canada",
                "index": 1,
                "pageprops": {
                    "page_image": "Investment_Industry_Regulatory_Organization_of_Canada_Logo.jpg",
                    "wikibase_item": "Q16987312"
                },
                "description": "organization",
                "descriptionsource": "central"
            }

However, if a go to https://en.wikipedia.org/wiki/IIROC I get redirected to https://en.wikipedia.org/wiki/Investment_Industry_Regulatory_Organization_of_Canada.

So why "IIROC" is not included in the redirects for "Investment_Industry_Regulatory_Organization_of_Canada"?

Thank you

You should continue your prop query until the batch is complete.

I reached the following result by continuing the query until https://en.wikipedia.org/w/api.php?action=query&format=json&prop=pageprops%7Cdescription%7Credirects&continue=%7C%7Cpageprops%7Cdescription&generator=search&redirects=1&rdcontinue=Financial_adviser%7C52889338&gsrsearch=iiroc&gsrlimit=10
