Perhaps you should try some spelling variations:
"philologica" » "philological", "philologie", "philologiae"
"philologiael" » "philologiae", "philologie", "philological"
"philologisch" » "philologische", "philosophisch", "philologie"
"philologists" » "philologie", "philologiae", "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: (("philologica" OR "philologiael") OR ("philologisch" OR "philologists"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"philologica\" or \"philologiael\") or (\"philologisch\" OR \"philologists\"))*".
• Removing quotes may allow a broader search: (( philologica or philologiael ) or ( philologisch OR philologists ))*.
