But it seems like it can only search in regex mode and not keyword.

Also does anyone know if there is a way to find the doc with the asset? I can't seem to click on the search result and it doesn't really tell me where it is.

Just to answer this as well. It seems like it can search some of the PDFs. It is likely some of my PDFs aren't parsable.

I guess I can answer my own question. Seems like it is only intended in std environment https://github.com/siyuan-note/siyuan/blob/928c1d476a4b398bdee3752cc950aed85838bf8f/kernel/util/ocr.go#L347

Can I ask if the maintainers have any reasons why it shouldn't work in docker? Thanks

Thanks for replying. This is exactly what I need. However, do you happen to know why I might not see those buttons?
