Perhaps you should try some spelling variations:
"failure patients analysis" » "failure agents analysis", "failure patterns analysis", "failure pigments analysis"
"failure point analysis" » "failure joint analysis", "failure conjoint analysis", "failure content analysis", "failure points analysis", "failure post analysis", "failure doing analysis"

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: (("failure patients analysis") OR ("failure point analysis")).
• Removing quotes may allow a broader search: (( failure patients analysis ) or ( failure point analysis )).
• Adding a wildcard symbol may retrieve word variants: (("failure patients analysis") or ("failure point analysis"))*.
