You can set ISEARCHDIR for yourself by putting a little wrapper function
around history-incremental-search-*.
hist-inc-search-save-direction() {
if [[ $WIDGET = *-forward ]]; then
typeset -g ISEARCHDIR=1
zle .history-incremental-search-forward "$@"
else
typeset -g ISEARCHDIR=-1
zle .history-incremental-search-backward "$@"
fi
}
zle -N history-incremental-search-forward hist-inc-search-save-direction
zle -N history-incremental-search-backward hist-inc-search-save-direction
I'm not sure I got the semantics of ISEARCHDIR the way you wanted them,
but you get the idea.
