Perhaps you should try some spelling variations:
mohan roy » mohon roy, mohan r, mohan rai
raja ram » raja ravi, raja m, raja roy
m mohon » m mohan, m morton, _ mohonk
m moxon » mr moxon, j moxon, m oxon
raja r » raja _, raja j, raja m

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