Perhaps you should try some spelling variations:
"failure patient analysis" » "failure patients analysis", "failure patent analysis", "failure latent analysis", "failure treatment analysis"
"failure event analysis" » "failure element analysis", "failure joint analysis", "failure point analysis", "failure events analysis", "failure recent analysis", "failure agent analysis"
"failure late analysis" » "failure latex analysis", "failure plate analysis", "failure later analysis", "failure rate analysis", "failure rates analysis", "failure state 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 patient analysis") OR ("failure event analysis"))) OR ("failure late analysis")).
• Removing quotes may allow a broader search: (((( failure patient analysis ) or ( failure event analysis ))) or ( failure late analysis )).
• Adding a wildcard symbol may retrieve word variants: (((("failure patient analysis") or ("failure event analysis"))) or ("failure late analysis"))*.
