Do you mean that there is no wordpress website out there whose default search facility does not retrieve content from RSS feeds? To be honest I think there must be a solution for this and there must be thousand of users who had to deal with this before, but unfortunately I have not found information about this.
I am currently managing my website with another CMS and to make it work, there was a need to write some lines in the controller.php file, but I don’t know how it could work in a wordpress scenario
