Perhaps you should try some spelling variations:
"support large international efforts." » "support large international airports.", "support large international energy.", "support large international airport.", "support care international efforts.", "support change international efforts.", "support three international efforts.", "support lars international efforts.", "support long international efforts.", "support land international efforts."
"support seed testing services." » "support seed existing services.", "support seed lending services.", "support seed training services.", "support needs testing services.", "support needy testing services.", "support self testing services.", "support field testing services."

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: "((\"support seed testing services.\") OR (\"support large international efforts.\"))~".
• Removing quotes may allow a broader search: (( support seed testing services. ) OR ( support large international efforts. ))~.
• Adding a wildcard symbol may retrieve word variants: (("support seed testing services.") OR ("support large international efforts."))*.
