You can currently search your saved sites by tag and using a more free-form search that includes site titles & descriptions as well as tags. We've toyed with the idea of full-text search & stuff like that but there are no immediate plans to add it.
When you say you would like to search by date, do you mean the date you saved a link on?

There isn't right now. If you know what you're looking for, try using the "search my sites" box at the top right of your screen.
We'll take some sort of sorting under consideration.
