If you only want to do this sometimes (since defaulting to search mode
for all completion is probably extremely annoying), you can bind it to
a separate key;

zle -C menu-select-search menu-complete _generic
zstyle ':completion:menu-select-search:*' menu select search
zstyle ':completion:menu-select-search:*' completer _oldlist _expand _complete
bindkey "^[M"  menu-select-search # alt-shift-m

or if you already have a key bound to start regular menu selection, eg
bindkey "^[m"  menu-select
(this requires no other setup, it's a stock widget)
then you can press ^R to enter the search mode from there, if you also do
bindkey -M menuselect '^R' history-incremental-search-forward
(this is handled specially in menu select mode, and won't actually
invoke history searching.)
