Completing words with hyphens with company

Question

I am using company buffer completion. But cannot get to match ligatures with hyphen in them. What can I do to complete parts containing hyphens?

Suppose I have the following text

;; This buffer is for-text that is not saved, and for Lisp-evaluation.
;; To create a file, visit it with C-x C-f and enter text in its buffer.

But entering for does not show for-text, and li does not show Lisp-evaluation.

This is the function that I am using

(defun company-sequencer ()
  "Place 'company feature in a ready operational state."

    (setq company-minimum-prefix-length 2)

    ;; Expand words with Dynamic Abbreviation
    (setq company-backends '(company-dabbrev company-dabbrev-code))

    ;; Explore text in current buffer, then in all open buffers
    (setq company-dabbrev-other-buffers 'all)
    (setq company-dabbrev-ignore-case 'keep-prefix)

    (setq company-dabbrev-code-other-buffers 'all)
    (setq company-dabbrev-code-ignore-case t)
    (setq company-dabbrev-code-everywhere t)) )
