Dear Peter,

Thank you very much for your answer. Your use case is indeed similar, if 
slightly more complex. I had hoped I could reuse the existing 
history-incremental-search-backward widget, only changing the history 
before calling it. The relevant command (which you also use in your 
widget) seems to be "fc -p <NEWHISTFILE>". As I understand it, this 
pushes the current history and replaces it with a new history, read from 
<NEWHISTFILE>. This approach actually works when I use the fc -p command 
on the command line before hitting Ctrl-R, but when I wrap it in a 
widget it does not work:

# Define shell function to be used as widget:

function accumulated-history-incremental-search-backward () {
     fc -p "${HOME}/.accumulated-history"
     zle .history-incremental-search-backward
}

# Tell zsh to use the function as a widget:

zle -N accumulated-history-incremental-search-backward

# Bind Ctrl-i to the widget:

bindkey "^I" accumulated-history-incremental-search-backward

Is there any particular reason why calling fc -p inside the widget does 
not affect the history search?
