Dear @capink,
I'm now using "Selection Modifier" to search
Search: New search
Search option: Select all book in current view (or another option)
If the search finds something, the action continues well. But if it finds nothing an error shows up
Code:
File "calibre\db\view.py", line 226, in index_to_id
IndexError: tuple index out of range
Since I plan to use this with "Timer" event, there will be a tons of error messages like this... because at the end of the action chain, some tags will be removed and it will affect the search result when the action chain is triggered again.
