I can not give a specific answer  to your problem,  I think that these
features  come with the 'readline' package.  I  don't know what can be
done from the Octave side. Perhaps  a workaround to solve your problem
is to grep the ~/.octave_hist file and cut-and-paste into the Octave's
command line.

I just want to point the wonderful history recovery mechanism that you
have if using the inferior-octave package under Emacs (due to (correct
me if I'm wrong) Kurt Hornik and JWE  itself).  First, you can recover
specific  lines  by  entering  the beginning   of   the line and  then
"<Ctrl-c><Ctrl-b>".  Includes  commands  of   previous sessions.    In
addition  you can use  all  the power of   'the Editor'  (just not  to
mention His name, see  

to find   the command in  the  buffer which  contains all  your Octave
session, and  edit it.  Documentation  of the Octave  package for 'the
Editor' comes with the Octave's manual.
