Perhaps you should try some spelling variations:
"cadth optimal use report" » "path optimal use report", "width optimal use report", "health optimal use report", "cadth optimal time report", "cadth optimal use reports", "cadth optimal user report", "cadth optimal lse report"
"CADTH optimal fused port" » "CADTH optical fused port", "CADTH optimal fixed port", "CADTH optimal based port", "CADTH optimal fused point", "CADTH optimal fused pnt"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("CADTH optimal fused port") OR ("cadth optimal use report")).
• Removing quotes may allow a broader search: (( CADTH optimal fused port ) or ( cadth optimal use report )).
• Adding a wildcard symbol may retrieve word variants: (("CADTH optimal fused port") or ("cadth optimal use report"))*.
