Q&A plugin, multisite search

Hello. I just created a multisite and am having issues with searching for content created by the Q&A plugin.

I downloaded the free Global Multisite Search plugin on WordPress and got that to work when searching for actual posts, but I cannot get question posts created by the Q&A plugin to appear in these results. Do you know of something I can do, perhaps an edit to this search plugin, to make this content appear in results? Thank you.
