Perhaps you should try some spelling variations:
"line segments feature analysis" » "line segment feature analysis", "line segment features analysis", "line segmental features analysis", "line segments texture analysis", "line segments capture analysis"
"line segments failure analysis" » "line segments figures analysis", "line effects failure analysis", "line prevents failure analysis", "line segments capture analysis"
"line events failure analysis" » "line events capture analysis", "line nets failure analysis", "life events failure analysis", "line event failure analysis", "nine events failure 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: (("line segments feature analysis") OR ((("line segments failure analysis") OR ("line events failure analysis")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"line segments feature analysis\") or (((\"line segments failure analysis\") OR (\"line events failure analysis\"))))".
• Removing quotes may allow a broader search: (( line segments feature analysis ) or ((( line segments failure analysis ) OR ( line events failure analysis )))).
• Adding a wildcard symbol may retrieve word variants: (("line segments feature analysis") or ((("line segments failure analysis") OR ("line events failure analysis"))))*.
