Perhaps you should try some spelling variations:
cadth optimal » width optimal, health optimal, wealth optimal
path optimal » h optimal, path options
pulse report » false report, false reports, case report
lse report » lee report, false report, leste report

Try widening your search to All Fields.

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) OR (path optimal)) lse report, 1927-0127") OR ("((cadth optimal) OR (path optimal)) pulse report, 1927-0127")).
• Removing quotes may allow a broader search: (( ((cadth optimal) OR (path optimal)) lse report, 1927-0127 ) or ( ((cadth optimal) OR (path optimal)) pulse report, 1927-0127 )).
• Adding a wildcard symbol may retrieve word variants: (("((cadth optimal) OR (path optimal)) lse report, 1927-0127") or ("((cadth optimal) OR (path optimal)) pulse report, 1927-0127"))*.
