Identify paragraphs using tags

[dorich]

Is it possible to create a query that finds tagged paragraphs. I see that this is possible using bullet lists and wonder if the same is possible with a plain paragraph within a note using a tag.
Not being a programmer I enlisted the help of ChatGPT but none of the suggestions work, for instance:
TABLE paragraph AS "Tagged Paragraphs" FROM "" FLATTEN split(file.content, "\n\n") AS paragraph WHERE contains(paragraph, "#testtag")
but produces no results. I get the feeling finding paragraphs isn't possible, having tried a lot of ChatGPT's variants, but would like to confirm.

Thanks.
