No post before the grid for search page

I already asked about his, but after a lot of tests, i finally managed to do it editing
pinboard_is_teaser()
I replaced
$offset = pinboard_get_option( 'archive_excerpts' );
with

{
if( is_search() )
$archive_excerpts = 0 ;
else
$offset = pinboard_get_option( 'archive_excerpts' );
}
