Perhaps you should try some spelling variations:
"line segment features analysis" » "line segment feature analysis", "line segment measures analysis", "line salient features analysis", "line element features analysis", "line recent features analysis"
"line segments failure analysis" » "line events failure analysis", "line segments feature analysis", "line segments figures analysis", "line segments capture 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: (("line segments failure analysis") OR ("line segment features analysis"))*.
• Removing quotes may allow a broader search: (( line segments failure analysis ) or ( line segment features analysis ))*.
