This kata was first. Closing.
this is true, but too much specific to JS. Won't be added (especially now)
Not a suggestion. And any easier katas based on this idea would not be interesting/original.

edit: resolved the wrong one...
Exactly! The task description doesn't imply that using RegExp naively (i. e. taking "searchText" as a valid regular expression) should work. Still, those RegExp-based solutions are being upvoted, but hey, that's life... ;)
Added in JS.
Added the following test case as well as random test cases. [Python]
test.assert_equals(processes('a','d',[['1','a','b'],['2','b','c'],['3','c','b']]), , 'You should return  when no path can be found.')
test.assert_equals(processes('a','d',[['1','a','b'],['2','b','c'],['3','c','b'],['4','c','d']]), ['1', '2', '4'])
