Perhaps you should try some spelling variations:
"support through integration efforts." » "support through innovation efforts.", "support through information efforts.", "support through international efforts.", "support through conservation efforts."
"support group integration theory." » "support group integration through.", "support group information theory.", "support group integration report.", "support grid integration theory.", "support run integration theory.", "support global integration theory.", "support from integration theory.", "support grant integration theory."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("support through integration efforts.") OR ("support group integration theory."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"support through integration efforts.\") OR (\"support group integration theory.\"))*".
• Removing quotes may allow a broader search: (( support through integration efforts. ) OR ( support group integration theory. ))*.
