I am a big fan of Windows Search when it comes to Windows OS platform. My first and most favorite use case of windows search is finding emails quickly. I have inbox of over 15GB distributed across multiple achieves of .PST file (Microsoft Outlook). Of course, I am referring to searching emails (in Microsoft Outlook) from those 15GB+ emails.
Lets look at the example of how to find email from Mr. X and sent to Mr. Y and cc to Mr. Z with attachment and containing word “confidential” in its body or attachment.
In windows search box, it is enough to type in following query,
from:Mr. X toaddress:Mr. Y ccaddress:Mr. Z hasattachment:true confidential
That's it. Easy and effective.
