The brain 8 had a configuration for searching attachments, including PDF's.
You can configure the maximum size of an attachment in order for it to be included in the search index.

Being able to searching attachments like PDF is very useful to me.

How does this work with the brain 9?
Even though there is no configuration for this, the brain does index the PDF's.
But, is there a size limit of the PDF?

And, are there plans to support indexing other filetypes as well (e.g. epub, azw3 etc)?

Thanks in advance.

TheBrain 9 utilizes the index of your underlying operating system. Anything that can be indexed by your OS is searchable by TheBrain.
