Our Universal Search feature can be found in the upper right corner of Sage ACT! 2012 and 2013.
This searches everything, even the text inside attached files and email. Unfortunately it cannot today create a lookup so can modify the fields or send a mail merge or any of the other tasks that a lookup is great for.
Is this something that is missing for you? If you want to be able to create a lookup from universal search results, KUDO THIS POST!!
