Where is a summary of search bar syntax?

Where is a summary of search bar syntax?

Is there a better description of
https://joplinapp.org/#searching

I got hits on notes containing the text “2017” back from a query for the text “2.17”.
So I was wondering about what other ignorant elements of the search syntax exist.

Thanks.

Hi,
searching “2.17” between quotes, I get the unique note containing this text.
