Perhaps you should try some spelling variations:
"philologisch" » "philologische", "philologiae", "philological"
"philologica" » "philological", "philologiae", "philologische"
"philologists" » "philologiae", "philological"
"philologie" » "philology"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"

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: (("philologisch" OR "philologica") OR (("philologists" OR "philologie") OR "philosophisch")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologisch\" or \"philologica\") or ((\"philologists\" OR \"philologie\") or \"philosophisch\"))".
• Removing quotes may allow a broader search: (( philologisch or philologica ) or (( philologists OR philologie ) or philosophisch )).
• Adding a wildcard symbol may retrieve word variants: (("philologisch" or "philologica") or (("philologists" OR "philologie") or "philosophisch"))*.
