Task names and project names are often strings of letters and numbers.
Currently, I’m having trouble searching for them.
The situation is as follows:
P2102345: Search OK
P210234, P21023, etc.: Search Unsuccessful

@ka_nishiyama - try adding a * at the end of your search term. I also had issues with this and I think that (mostly) resolved for me. Agreed that it should search substrings by default.
@Stephen_Li , Thank you very much. 
I have successfully completed the desired search.
In some cases, it seems that this may not be possible.
