The Thunderbird Global Search is great. I have many email accounts and folders and do not always remember where an email is located, so for me, Global Search is much faster than Classic Search.
I suppose faceted search may be useful if something is misspelled or you do not remember the tense. More often than not, I want an exact match search, not one where multiple words are included.
Please add the functionality of double quotes or other method to do an exact match search in Global Search.
