I would suggest you start with the simplest approach, which is that the search text box will always be shown, either when it's empty and also when a user has entered data (which will continue being shown in it). In this way a user will be able to see what search term they've already searched on, and/or modify their search as needed.

Proper requirements don't dictate design. This is especially important when, like in this case, the "requirement" is for something that the platform doesn't inherently do. 
 You can set it up such that the search box doens't appear until you hit the "search" icon, that part is relatively easy. However there's nothing in the SAIL interface design setup that would allow you to arbitrarily effect form elements simply by clicking outside the element, so you'll have to figure out a different implementation that will satisfy your requirements. 
 Again, requirements should be along the lines of "have the ability to...", not "should have this exact design...". What are the users unable to accomplish without the search box disappearing when clicking outside of it, that they can't accomplish in a different configuration that will actually work in Appian?
