A stupid bug caused the issue, I will deploy a newer version now.

@Sil @MartinR Both example queries you mentioned are now getting expected results. Please check them out. And the new demo produce much more results.

@WeiZhong Sounds good, will try once I get home.

I have also pulled your AoPS changes as well as some mathquill updates to the most recent code. Also the project for which I sent you the invitation is now moved to a new place, so check out the new project here: github.com/t-k-/a0-private/invitations (it is also a private one).

Now I am going to shutdown the new demo temporarily and deploy the changes I just pulled. Give me just 5 minutes...

It is up now, and the changes you did previously should have been applied.

Strange, I find if I type upperscript, the KaTeX renders it way above to the top of the editbox. I need to investigate this...

Alright, simply a hard refresh will fix this issue.

@Sil, I have updated a documentation page as a thankful note to your contribution.

@WeiZhong The query results look good to me now, gj. Thanks for adding me, although that was a little contribution ;)
