Hey there. Thanks for the response.

1. I already did tried the 'Anchor hash' option before but it only seems to work with markdown links, when you're exporting an entire notebook. Which means if you're exporting a single document the markdown links to other documents are lost and SiYuan links are used instead in the markdown file. Also, lets consider that it can't be helped since we are selectively exporting a single document at the time. But even if you just export a single document into markdown, SiYuan also exports all of its subdocuments. Which if it does, then in order to introduce consistency, it should also convert their in between references or reference blocks to markdown links. Currently it directly exports the SiYuan links, which only seems to work in SiYuan. I hope the attached demonstratoin clarifies what I am trying to highlight here.
2. There was a typo from my end and I would like to correct the format I mentioned before. It actually is [Annotation Text](assets/Annotated_PDF-date-id.pdf#page={number}). This format is standardly applicable in many pdf viewers such as Adobe Acrobat and even web based implementations of Google Chrome, Firefox and Microsoft Edge. However, it really isn't a standard and is only just widely supported, therefore it’s not guaranteed to work in all environments. But it also doesn't break anything and in cases where it doesn't work, this hyperlink format still has the same behaviour as the current one implemented in SiYuan. So It's a plus to use it since it is widely supported in major pdf viewers. I have attached a demonstration for web based pdf viewers with this format for a link generated through SiYuan.

Got it!. Thank Youu

That's a shame. Was really looking forward to some replacement for Obsidian's DataView 😭

Yes, would love to have some kind of docs to get more insights into the search power using SQL.
Can you please share what you have found about querying finished and unfinished tasks?
It would be highly appreciated.
