Yes!  This is an exciting enhancement made possible by the new mobile first design.  There is now a full-featured search tool incorporated into the Account Details (transaction history) feature in the new look for It's Me 247.

At the top of that page there is a new "search transactions" box where you can enter an amount, part of the transaction description, a check #, or any other text that appears in the transaction list to find all matching items.  For more specific search, you can use the Advanced button to choose from a list of common transaction types, or specify a dollar amount range.
