Perhaps you should try some spelling variations:
12 martin » 12 marine, 12 marie, 12 mating
2 martin » 2 marine
12 main » 12 mai, 12 making, 12 marine
f 1889 » 1 1889, 2 1889
_ 1889 » _ 1880, _ 1819, _ 1849

Try widening your search to All Fields.

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: %22heidegger%((c martin) OR (((2 martin) OR (((12 martin) OR (12 main)))))) %((2((f 1889) OR (_ 1889))) OR (((f 1889) OR (_ 1889))))-1976%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22heidegger%((c martin) or (((2 martin) or (((12 martin) or (12 main)))))) %((2((f 1889) OR (_ 1889))) or (((f 1889) OR (_ 1889))))-1976%22".
• Adding a wildcard symbol may retrieve word variants: %22heidegger%((c martin) or (((2 martin) or (((12 martin) or (12 main)))))) %((2((f 1889) OR (_ 1889))) or (((f 1889) OR (_ 1889))))-1976%22*.
