This doesn't quite work as expected. At least if you're used
to the tcsh model. It only searches for the first word on the
line. So if your do this:

# echo Hello
# echo doh
# echo H<up-line-or-search>  -> displays "echo doh"

The tcsh version is much more useful, so I ended up
implementing a copy. Put this somewhere in your startup
files:

-----------------------------------------------------------
_tcsh-history-search-init () {
    if [[ $HISTNO == $HISTCMD || \
          $CURSOR != $#BUFFER || \
          $history[$HISTNO] != ${HISTORY_SEARCH}* || \
          $history[$HISTNO] != ${LBUFFER}* ]]; then
        HISTORY_SEARCH="$LBUFFER"
    fi
}

tcsh-history-search-forward () {
    _tcsh-history-search-init
    zle .history-search-forward $HISTORY_SEARCH
}

tcsh-history-search-backward () {
    _tcsh-history-search-init
    zle .history-search-backward $HISTORY_SEARCH
}

zle -N tcsh-history-search-forward
zle -N tcsh-history-search-backward
-----------------------------------------------------------

Now you can bindkey it to what you like:
bindkey "^[p" tcsh-history-search-backward
