I found a way to do this. I did the following
1) Backed up the calibre database (metadata.db)
2) Downloaded
SQLite Administrator
3) Ran the following SQL against the database:
Quote:
delete from books_tags_link
where id in
(
select id from books_tags_link
where tag in
(
select tag from books_tags_link
group by tag
having count(tag) < 30
)
)
|
This deleted all tags that are on less than 30 books.
