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

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