Case sensitive search not working

Anki Help
1

Eg, using same search from this post, re:(?-i)RA in the browser for me brings up all “RA” as well as “ra”
How to do case-sensitive searches in browser?

Also I have to enclose it in double-quotes, “re:(?-i)RA”, or it changes the spacing when I hit enter and returns no results.
Has there been some change to regex search from before? Or how do I do a case-sensitive search?

You’re right, it needs to be quoted. Other than that, "re:(?-i)RA" works for me.

I took another look if it works for other people, and noticed that there is actually hidden formatting in the cards that come up, which also have “ra” in the actual visible text, so I thought that was what it was finding! I’ll have to use some regex to remove this formatting which came in for some reason with the importation.
