Thank you for your idea. `company-search-mode' is a minor mode, and
according to the notes here [1], I changed your function to the
following:

  (defun hz-company-search ()
    (interactive)
    (if (bound-and-true-p company-search-mode)
    (company-search-abort)
      (company-search-candidates)))

  (define-key company-mode-map "\t" #'hz-company-search)

Based on my testing, it doesn't work as expected.
