Perhaps you should try some spelling variations:
"failure treatment analysis" » "failure investment analysis"
"future treatment analysis" » "future investment analysis", "pre treatment analysis"
"failure patient analysis" » "failure patients analysis", "failure patent analysis", "failure latent analysis"

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: (("failure patient analysis") OR ((("failure treatment analysis") OR ("future treatment analysis")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"failure patient analysis\") or (((\"failure treatment analysis\") OR (\"future treatment analysis\"))))".
• Removing quotes may allow a broader search: (( failure patient analysis ) or ((( failure treatment analysis ) OR ( future treatment analysis )))).
• Adding a wildcard symbol may retrieve word variants: (("failure patient analysis") or ((("failure treatment analysis") OR ("future treatment analysis"))))*.
