Perhaps you should try some spelling variations:
"basen allgemeine" » "gasen allgemeines", "fragen allgemeine", "deren allgemeine"
"feld allgemeine" » "felder allgemeine", "umfeld allgemeines", "falle allgemeine"
"ugld allgemeine" » "und allgemeine", "gold allgemeines", "und allgemeines"

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: (((("feld allgemeine") OR ("ugld allgemeine"))) OR ("basen allgemeine")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"feld allgemeine\") OR (\"ugld allgemeine\"))) or (\"basen allgemeine\"))".
• Removing quotes may allow a broader search: (((( feld allgemeine ) OR ( ugld allgemeine ))) or ( basen allgemeine )).
• Adding a wildcard symbol may retrieve word variants: (((("feld allgemeine") OR ("ugld allgemeine"))) or ("basen allgemeine"))*.
