I’m trying to link multiple notes to a single note with a single command or step.
Basically I’m searching for a phrase that exists in a specific type of note. Then link all those found notes to a single new note to create an ‘index’.
Is there a way to do that without having to add the link to each individual note?
I’ve not heard of any plugin capable of adding that link to multiple notes, but if it’s a given phrase which is used in the linked note, you might see all the other reference as linked mention and can click on them from there to create links.
I haven’t tried it, but, there is a plugin called " obsidian-multi-properties", which apparently allows adding a property (like tag) to all notes in a Search result
so, perhaps you could search for your phrase text, add a new tag to the results, then add an embedded search to your index page to query for the new tag
