Perhaps you should try some spelling variations:
cadth optimal » path optimal, width optimal, health optimal
"CADTH optimal user report" » "CADTH optimal use report", "CADTH optimal upper report", "CADTH optimal fused report", "CADTH optimal cluster report", "CADTH optimal user reporting", "CADTH optimal user support"
"CADTH optimal user port" » "CADTH optimal use port", "CADTH optimal upper port", "CADTH optimal fused port", "CADTH optimal user part", "CADTH optimal user portal", "CADTH optimal user point"

Try widening your search to All Fields.

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"CADTH optimal user report\") OR (\"CADTH optimal user port\"))".
• Removing quotes may allow a broader search: (( CADTH optimal user report ) OR ( CADTH optimal user port )).
• Adding a wildcard symbol may retrieve word variants: (("CADTH optimal user report") OR ("CADTH optimal user port"))*.
