Search functionality has never worked correctly since I’ve been a Zoho member. 

A simple “USPS” search in the Trash folder returns zero results.  Then, searching across apps returns zero results.  But yet, if I view the Trash folder as normal, I can see several emails with the “USPS” language.  (See three photo attachments.)

I receive at least two emails daily that contain the “USPS” language daily.  So, if anything, the search should be populating some results.

I've read a other posts over the years, but none of the solutions provided ever worked (seems like search issues are an ongoing issue?)

Any ideas?
