How to Search Email and Attachments in Zoho CRM?

How do I search emails that are tracked to Zoho CRM (via Outlook Plugin) and documents that are attached to CRM?  When I use the search function I do not seem to be able to get these as results.  I apologize if this is something fairly obvious, but I am new to Zoho CRM.  Thank you.
