Perhaps you should try some spelling variations:
"le primer" » "le primier", "de primer", "e primer", "late primer", "le primierr", "le princer"
"le prime" » "late prime", "le primier", "le prince"
"_ primer" » "_ prime", "_ primes", "_ primary"
"klein prime" » "kleine prime"

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: (("klein prime") OR ((((("le primer") OR ("le prime"))) OR ("_ primer")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"klein prime\") or (((((\"le primer\") OR (\"le prime\"))) or (\"_ primer\"))))".
• Removing quotes may allow a broader search: (( klein prime ) or ((((( le primer ) OR ( le prime ))) or ( _ primer )))).
• Adding a wildcard symbol may retrieve word variants: (("klein prime") or ((((("le primer") OR ("le prime"))) or ("_ primer"))))*.
