Ticket Notes should be Searchable

Ticket notes usually contain key information regarding a customer's repair and sale history. Many users have encountered a situation where they need to pull up a ticket, but they don't know any details for the ticket: customer name, phone number, etc, but they recall specific notes that were on the ticket. Things are search-driven these days. Users should be able to find the information they leave on a ticket, rather than that information becoming nearly useless or unable to be referenced after closing out a ticket.
