Folds are useful to temporarily hide text that you don't currently need to see. By default, when you search for text, each fold containing a search hit automatically opens when you find the hit. This behavior is controlled with the 'foldopen' option (abbreviated to 'fdo').
To search only in open folds (unfolded text):
:set fdo-=search
With the above, a search shows one hit per fold that contains the search target. The fold is not opened, and is only found once, even if it contains several instances of the search target.
You can also perform commands only on lines in open folds. For example, the following command will change every 'old' to 'new', but only in lines that are not folded:
:folddoopen s/old/new/ge
With :folddoopen, each unfolded line is marked. Then the command (s/old/new/ge) is executed on each marked line. Therefore the s/// command has no range (it operates on the current line), and it has the e flag so no error is shown if a line does not contain 'old'.
