"history-search-backward" but ignore sudo prefix in zsh?

According to this page: https://zsh.sourceforge.io/Doc/Release/Zsh-Line-Editor.html history-search-backward: "Search backward in the history for a line beginning with the first word in the buffer." But when command is prefixed with sudo that breaks everything. Can I make zsh ignore sudo for this command? Also want to apply same thing for history-search-forward
