Perhaps you should try some spelling variations:
"andrew a.r watson" » "andrew a.l watson", "andrew barr watson", "andrew baker watson", "andrew j.r watson", "andrew r.r watson", "andrew dr watson"
"andrew 3.6 watson" » "andrew 12.6 watson", "andrew a.l watson", "andrew 2.3 watson", "andrew c.s watson", "andrew c.w watson"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"andrew a.r watson\") OR (\"andrew 3.6 watson\"))".
• Removing quotes may allow a broader search: (( andrew a.r watson ) OR ( andrew 3.6 watson )).
• Adding a wildcard symbol may retrieve word variants: (("andrew a.r watson") OR ("andrew 3.6 watson"))*.
