Perhaps you should try some spelling variations:
"specifying open" » "specifying agent", "specifying complex", "specifying color"
"specific open" » "specifics open", "specific organ", "specific speed"
"specify open" » "special open", "specifics open", "specify event"

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: (("specific open") OR ((("specify open") OR ("specifying open")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"specific open\") or (((\"specify open\") OR (\"specifying open\"))))".
• Removing quotes may allow a broader search: (( specific open ) or ((( specify open ) OR ( specifying open )))).
• Adding a wildcard symbol may retrieve word variants: (("specific open") or ((("specify open") OR ("specifying open"))))*.
