RT Dashboards are a customized RT web page, with 1 or more sections defined; for displaying desired groupings of RT data and functions. Dashboards typically include sections such as :
Users can create custom personal Dashboards, and Departments can create and share Departmental Dashboards to provide easy access to their users.
A defined Dashboard can also be "subscribed" to. Then, you can define when you want to receive an email containing that Dashboard's current view.

This option of searching has existed prior to RT 4.4, but it now indexes and returns your results faster.
Once you have made a simple search, you may also then edit that search in the full RT query builder, to refine the search with other attributes(Subject, owner, Queue, status etc) or add a date range. Once you have a search query you like, you can save that search for reuse later or for inserting into a Dashboard.
