Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologische", "philological"
"philologists" » "philologischs", "philologisches", "philologicals", "philological"
"philologie" » "philology"
"philologica" » "philological", "philologisch", "philologische"
"philologicals" » "philologicalls", "philologischls", "philologischels", "philological", "philologically", "philologicis"
"philologischs" » "philologisch", "philologische", "philologischen"

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