[Perlfect-search] how to exclude some pdf files from the index

[Yves Hanotiau]

Hello,

I'm new on the list.
I read that it was in the "readme documentation" that it was possible to
exclude some HTML files with the following metatag : <meta name="robots"
content="noindex">.

Is it possible to exclude some PDF files from the index ?

thanks in advance.
