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