Perhaps you should try some spelling variations:
raja hari » raja ravi
mohan roy » mohan r, mohan rai, roman roy
mohon roy » cohen roy
mon roy » von roy, kwon roy
raja m » raja _, raja j, raja r

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: "((\"((raja hari) OR (raja halli)) mohan roy\") or (\"raja m ((mohon roy) OR (mon roy))\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((raja hari) or (raja halli)) mohan roy\\") or (\\"raja m ((mohon roy) OR (mon roy))\\"))\"".
• Removing quotes may allow a broader search: (( ((raja hari) or (raja halli)) mohan roy ) or ( raja m ((mohon roy) OR (mon roy)) )).
