Hi dirkschrama,
So it certainly should work – but depends on the context of your search. For instance, if you are viewing the month of October and Color Obstacle Run takes place in November then it won’t return a match. However, within the upcoming list view it definitely should return a match.
I tried visiting the URL you shared when you created this thread to see if I could check out the problem but I couldn’t actually locate The Events Calendar … can you point me in the right direction?
Thanks!
