That query description shows a single term: Snew dolphin

This means you set title/S as a boolean prefix, which I doubt is what
you want - titles are better treated as free text fields.

This means you are indexing the title as free text, so if you change:

$qp->add_boolean_prefix("title", "S");


$qp->add_prefix("title", "S");

then it will probably start working as you want.
