Perhaps you should try some spelling variations:
"specimen histological polemical" » "specimen histological cortical", "specimen historical political", "specimen histological molecular", "specimen pathological polemical", "special histologic polemical", "aspects histological polemical"
"specimens philological polemical" » "specimina philologica polemical", "specimen pathological polemical", "specimina philologiae polemical", "specimens philological philomedical", "specimens philosophical political", "specimens philological critical"
"species pathologic slavicae" » "species philologica slavicae", "species philologiae slavicae", "specific pathologic slavicae", "species pathogenic slavicae", "specimen pathological slavicae"

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: (("species pathologic slavicae") OR ((("specimen histological polemical") OR ("specimens philological polemical")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"species pathologic slavicae\") or (((\"specimen histological polemical\") OR (\"specimens philological polemical\"))))".
• Removing quotes may allow a broader search: (( species pathologic slavicae ) or ((( specimen histological polemical ) OR ( specimens philological polemical )))).
• Adding a wildcard symbol may retrieve word variants: (("species pathologic slavicae") or ((("specimen histological polemical") OR ("specimens philological polemical"))))*.
