Perhaps you should try some spelling variations:
"le primer" » "le primier", "le prime", "de primer", "le pricer", "le crimer"
"_ primer" » "_ prime", "_ primes", "_ primary", "_ pricer", "_ crimer"
"_ crimer" » "_ crime", "_ crimes", "_ crimea"
"klein prime" » "kleine prime", "klein price", "klein crime"

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