Perhaps you should try some spelling variations:
"philologist" » "philologisch", "philologie", "philologica"
"philologists" » "philologischs", "philologies", "philologicas", "philologie", "philological"
"philologiae" » "philologie"
"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 "philologiae") OR ("philologists" OR "philologischs")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologist\" or \"philologiae\") or (\"philologists\" OR \"philologischs\"))".
• Removing quotes may allow a broader search: (( philologist or philologiae ) or ( philologists OR philologischs )).
• Adding a wildcard symbol may retrieve word variants: (("philologist" or "philologiae") or ("philologists" OR "philologischs"))*.
