I usually take daily notes and are categorized under a topic.

I want to go through a specific category and want to get those in one single buffer (search or otherwise) with the contents.

So let's say I have a category country, I want to revisit all the details under this category.

I am using spacemacs and projectile. A project search or org-roam-find usually lets me search the header but doesn't say whats in the content.

Options I know of -

1. Creating an index of country headers and creating its own org-id for org-roam and visiting them manually

2. org-transclusion, where I could include all the same categories in one buffer and that would let me explore the content.

What I am looking for specifically is something that would not require me to make changes like above which would require creating org id for categories which I can use in a buffer. I want a simple approach where a search query would give me what I am looking for in a separate buffer.

Thanks in advance!
