Perhaps you should try some spelling variations:
"scientific description" » "scientific descripcion", "scientific descriptivo", "scientific descriptiva"
"cientifica description" » "cientifica descripcion", "cientifica descriptivo", "cientifica descriptiva", "cientificas description"
"cientifico description" » "cientifico descripcion", "cientifico descriptivo", "cientifico descriptiva", "cientificas description"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("scientific description") OR ("cientifica description"))) OR ("cientifico description"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"scientific description\") OR (\"cientifica description\"))) OR (\"cientifico description\"))".
• Removing quotes may allow a broader search: (((( scientific description ) OR ( cientifica description ))) OR ( cientifico description )).
• Adding a wildcard symbol may retrieve word variants: (((("scientific description") OR ("cientifica description"))) OR ("cientifico description"))*.
