AB 4.0.8 Categry bug on frontend

[RobertG]

A new error: when I disable "written by" for the books, on the frontend book page I get
Warning: Undefined variable $description in /components/com_abook/views/book/tmpl/default.php on line 413 and no description is displayed.
When I enable it, There are no more errors, but the description is preceded by 'Written by Robert Gastaud' (the author of the description), which I don't want to display. How can I hide this text?

I fixed 2 errors:

• filters in category view
• smart search index

Please try to install 4.0.9 version
Thanks

I will publish the fix to the next version

[RobertG]

Thank you, Federica!

I have 468 books, but only 50 were indexed.
What could explain this limitation?

[federica]

Thank you too

Go to Smart search configuration->index->Indexer Batch Size
This parameter is probably set to "50"

[RobertG]

OK, it's true, nut isn't there a risk of an error if I increase?
I set it to 100, and 100 books are now indexed – no more. Even If I restart the indexation.
Why aren't the following being sought?

[federica]

Joomla settings allow you to limit the index to avoid uncontrolled database growth and excessive workload in generating search results. The "Indexer Batch Size" value depends on your server's performance.
