search in org-sparse-tree for multiple files

search in org-sparse-tree for multiple files

Hi,
I can't seem to use the M-g M-n keys to jump to occurrences in sparse tree search for second org file within same Emacs window.
If I search first file by pressing C-c / r <regex> RET and then search second file by pressing C-c / r <regex> RET, I'm not able to jump to occurrences in that second file by pressing M-g M-n.  I get a message saying "No more matches" even though there are matches.  If I close the first file buffer, then I am able to use M-g M-n to jump to occurrences in the second file.
Does anybody know what I may be missing?
I'm using org mode version 9.6 in Emacs 28.2 on CentOS7.

`org-occur-next-match' does not support multiple buffers.
Looking at the docstring of `next-error-function', I am also not sure if
we need to support this there. The docstring talks only about the
current buffer.

What might be relevant is `next-error-find-buffer-function' - a user
customization you may want to set.

Generally, it is unclear for me how to implement multiple buffers
support for org-spare-tree. Ideas and patches welcome.

I'm assuming "current buffer" is the buffer which I can currently type input into.  The current buffer is not finding next occurrence of search string by pressing M-g M-n.  Is this expected?

Could you please elaborate?
What exactly you did and what do you expect to happen?

 I think I found a solution but here are the steps in case others have the same problem:
* First, I open an org file in Emacs.* I then create a sparse tree using a regular expression.* I then type M-g M-n to move to the next occurrence of my search string but it doesn't work.  I get a message saying "user-error: Moved past last grep hit".
* I kill the pre-existing "*grep*" buffer in Emacs.
* I then try M-g M-n again and it works.

Writing out these steps got me thinking that there might be an option in compilation mode to switch buffers when finding next error.  I looked in the compilation mode section of the Emacs manual and found next-error-select-buffer that switches buffers when searching for errors.  I also just realized that you mentioned next-error-find-buffer-function configuration variable in an earlier post.  I'll try that as well.
You can consider my question answered.  Thanks for the help.
