Perhaps you should try some spelling variations:
biometric documentation » metric documentation, biomedical documentation, forensic documentation
documentation a » documentation _, documentation fast
star based » snar based, starch based, state based
stay based » state based, assay based, stack based
sar based » qsar based, snar based, ar based
a curtan » a curran, _ curtain, _ cartan

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((star based) OR (sar based))) or (stay based)) biometric documentation a curtan-metragem~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((star based) OR (sar based))) OR (stay based)) biometric documentation a curtan-metragem*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((star based) OR (sar based))) or (stay based)) biometric documentation a curtan-metragem*".
