Perhaps you should try some spelling variations:
def » defi
deaf » leaf, deal, dean
leppard" » leopard", peppard", lippard"
lepard" » leopard"
peppered" » pepper"
tempered" » temper"
sheppard" » shepherd"

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: "(def or deaf) ((leppard" OR lepard") or ((peppered" OR tempered") or sheppard")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"(def or deaf) ((leppard\" or lepard\") or ((peppered\" OR tempered\") or sheppard\"))".
• Removing quotes may allow a broader search: (def or deaf) ((leppard or lepard ) or ((peppered OR tempered ) or sheppard )).
• Adding a wildcard symbol may retrieve word variants: "(def or deaf) ((leppard" or lepard") or ((peppered" OR tempered") or sheppard"))*.
