What I’m trying to do
I am looking to replace the “Index Notes Plugin” https://github.com/adanielnoel/obsidian-index-notes with the new “Bases” feature, has anyone tried that yet?
Things I have tried
I am not running 1.9 so I can’t try it…
No, I don’t think that bases can be used for that.
Bases produces only tables as results, in which each row represents a note (an alternative view transforms each row in a separate card, but in essence the result is tabular too). It cannot, at least currently, generate hierarchical output.
You can use bases to generate a table which list all the notes with a particular tag, yes, but it cannot recurse into nested tags, and you cannot generate a metaindex (unless it is enough for you to get a table with all the notes which contain an index).
I think dataview, and in particular dataviewjs, could be used to generate the same kind of output than index-notes, but it would not be trivial.
