Bing custom search API not finding super boosted site
I am working with the Bing custom search API, and I am having an issue with finding one of the site that have been super boosted, mainly it will not show up regardless of what search I execute.
Upon further investigation, I found that HTTP based site hosted by this organization are found, however, HTTPS based sites are not. I've also investigated searching this site using standard Bing and the HTTPS based site is found. Also, experimenting with other sites and queries, this problem does not appear to be affecting any other site.
Is there anything that can be done on our end, or on the site's organizations end? This organization is a major contributor, and ignoring it is not an option for us.
Thanks for any assistance.
