Searching in Zendesk works as you would expect; you enter words you wish to search for, and Zendesk returns all items that contain ALL of the words entered. The result set is ordered intelligently, e.g. tag matches are ranked higher than content matches. Items included in the search are users, groups, organizations, tickets and topics.
In addition, Smart Search offers various operators and property keywords. With Smart Search you can combine your free text search queries with smart queries and perform searches such as HP driver assignee:me, priority>normal and email:company.com. Embracing Smart Search will really speed up your day-to-day work routines.
There are some property keywords that you can use for customized search results. Keywords should be entered after the query and follow this format: keyword:value keyword:value or keyword:value keyword:”value1 value2” as any values with spaces must be surrounded by quotes.

type:user email:company.com - search for users from "company.com
tags:stuff - search for tickets or topics tagged with 'stuff'
tags:"more stuff" - search for multiple tag
submitter:123 - search by id
submitter:"Morten Primdahl" - search topic/ticket submitter by full name
submitter:morten - search submitter by partial name
submitter:morten@zendesk.com - search submitter by email address
The rules for submitter search are identical for requesters and assignees.
