Perhaps you should try some spelling variations:
"irish secretary" » "its secretary", "first secretary", "arms secretary"
"home secretary" » "hope secretary", "home secretary's", "rose secretary"
"his secretary" » "its secretary", "chief secretary", "solis secretary"

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