Calibre Regular Expressions and Authors With More Than One Book

[Incanus]

Hello:

I'm trying to check authors on my (rather extensive) Calibre library, and I'd like to know what the regular expression would be to list/filter/show ebooks of authors that have more than one ebook (listed on the library, that is).

Awaiting your kind reply,

[INCANUS]

Just use the tag browser:

https://manual.calibre-ebook.com/gui.html#tag-browser

The Tag browser allows you to easily browse your collection by Author/Tags/Series/etc. If you click on any item in the Tag browser, for example the author name Isaac Asimov, then the list of books to the right is restricted to showing books by that author. You can click on category names as well. For example, clicking on “Series” will show you all books in any series.

Or check out the Author Book Count plugin

A search can look for a count

Dates and numeric fields support the relational operators = (equals), > (greater than), >= (greater than or equal to), < (less than), <= (less than or equal to), and != (not equal to). Rating fields are considered to be numeric. For example, the search rating:>=3 will find all books rated 3 or higher.

You can search for the number of items in multiple-valued fields such as tags. These searches begin with the character #, then use the same syntax as numeric fields. For example, to find all books with more than 4 tags use tags:#>4. To find all books with exactly 10 tags use tags:#=10.

Series indices are searchable. For the standard series, the search name is ‘series_index’. For custom series columns, use the column search name followed by _index. For example, to search the indices for a custom series column named #my_series, you would use the search name #my_series_index. Series indices are numbers, so you can use the relational operators described above.
