Perhaps you should try some spelling variations:
"research second paper" » "research section paper", "research scope paper", "research selected paper", "research second pair", "research second part", "research second parts"
"research second phase" » "research section phase", "research scope phase", "research selected phase", "research second part"
"research write papers" » "research white papers", "research written papers", "research site papers", "research white paper", "research waste papers"

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: (((("research second paper") OR ("research second phase"))) OR ("research write papers")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"research second paper\") OR (\"research second phase\"))) or (\"research write papers\"))".
• Removing quotes may allow a broader search: (((( research second paper ) OR ( research second phase ))) or ( research write papers )).
• Adding a wildcard symbol may retrieve word variants: (((("research second paper") OR ("research second phase"))) or ("research write papers"))*.
