I've been having better results using advsearchKeywords search instead of explicitly specifying a title search (which is much more strict and fails on things like numbers prefixed etc.). Author can still be specified which results in a more flexible title search still sensibly constrained when author known.
Nice side effect is that advsearchKeywords= survives when searching the .com site from outside the US - unlike title=.
