Perhaps you should try some spelling variations:
"specimen histological polemical" » "specimen philological polemical", "specimen histological cortical", "specimen historical political", "specimens philological polemical", "specimen pathological polemical", "special histologic polemical"
"species pathologic slavicae" » "species philologica slavicae", "species philologiae slavicae", "species pathogenic slavicae", "specimen pathological slavicae", "special pathologies slavicae"
"specific pathologic slavicae" » "specific philologica slavicae", "specific philologiae slavicae", "specific pathological slavicae", "specific pathologies slavicae", "specific pathology 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 ("specific pathologic slavicae"))) OR ("specimen histological polemical")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"species pathologic slavicae\") OR (\"specific pathologic slavicae\"))) or (\"specimen histological polemical\"))".
• Removing quotes may allow a broader search: (((( species pathologic slavicae ) OR ( specific pathologic slavicae ))) or ( specimen histological polemical )).
• Adding a wildcard symbol may retrieve word variants: (((("species pathologic slavicae") OR ("specific pathologic slavicae"))) or ("specimen histological polemical"))*.
