[misc] Searching in calcurse

Hello,

I'm trying to learn how to search my calendar in calcurse. I have not found 
anything from within the calendar.  What I have found is: 

calcurse -Q --days 365 --search='Thanksgiving'

So that works but I want to do case insensitive searches. The only thing I 
have found that works is:

calcurse -Q --days 365 --search='[tT][hH][aA][nN][kK][sS]'

A bit awkward for casual searching.  Am I missing something simpler?
I tried:
--search='(?i)thanks'
--search='/thanks/i'
They returned nothing.

Thanks for any tips you can provide.

Donnie
