2 different search boxes (custom post type and regular)

Hi,

I have this exact issue: http://wordpress.org/support/topic/plugin-relevanssi-a-better-search-2-diferent-searchs-with-2-diferent-filters?replies=19

The thread is old and it looks like the new Relevanssi version doesn’t have a way to change “All public post types” to “Everything”. At least, I can’t find it.

I have 2 search boxes:

1. Blog search. When I use it I get this kind of URL: http://site.com/?s=term, but it also displays matching custom post types.

2. Custom post types: http://site.com/?s=term&post_type=product
It displays only custom posts, as needed.

Any way to fix this?

Thanks
