Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologie", "philologica"
"philologists" » "philologischs", "philologies", "philologicas", "philologie", "philological"
"philologiae" » "philologie"
"philologies" » "philologie", "philologien", "philologiques"

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