Global search: some Chinese character cause CRASH

I'm a heavy user from China. There're hundreds of notes by Chinese in my account. When I search for "的", which means "of", the most frequent word, Simplenote exits every time. Another account has only tens of notes, doing same thing dosn't exit.

Edition: 2.11
OS: 11.0.1 and 10.15.4

Start by reproducing the crash in the macOS app by searching global notes for the Chinese character "的" with an account containing many notes, then compare it with an account containing fewer notes. Use the crash output and search behavior to locate the failing search path; done means the search completes without Simplenote exiting.
