Perhaps you should try some spelling variations:
"philologisch" » "philologica", "philological"
"philologische" » "philologicae", "philologicale", "philosophische", "philological", "philologica"
"philologisches" » "philologicaes", "philologicales", "philosophisches", "philologicals", "philologicas", "philologischen", "philologischer", "philologischem"
"philosophisch" » "philosophische", "philosophischen", "philosophischer"
"philologie" » "philology"
"philologists" » "philological"

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