Perhaps you should try some spelling variations:
"life argument structure analysis" » "life document structure analysis", "life argument structural analysis", "line argument structure analysis", "line arguments structure analysis", "like arguments structure analysis"
"line segment cost analysis" » "line segment content analysis", "line segments cost analysis", "line segment case analysis", "line segment across analysis", "line segmental post analysis"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"life argument structure analysis\") OR (\"line segment cost analysis\"))".
• Removing quotes may allow a broader search: (( life argument structure analysis ) OR ( line segment cost analysis )).
• Adding a wildcard symbol may retrieve word variants: (("life argument structure analysis") OR ("line segment cost analysis"))*.
