The search api is asynchronous so what you need to do is connect
functions to signals.  I think you want something like the following:

def remove_debug_statements():
    """"""

    doc = wingapi.gApplication.GetActiveDocument()
    f = doc.GetFilename()
    searcher = wingapi.CAPISearch("^.+# debug-assist$", match_case=True,
search_style="regex")
    def process_matches(filename, match_list):
        for lineno, linestart, line_text, line_matches in match_list:
            # Do something with the matches for the line

    searcher.connect('match', process_matches)
    searcher.SearchFile(f)
