Perhaps you should try some spelling variations:
information documentation » international documentation, information presentation, information documents
squared euclidean » spaces euclidean, space euclidean
documentation a » documentation _, documentation fast
spaces » dspaces
ddspaces » dddspaces
space » dspace

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: information documentation a ((squared euclidean) OR ((spaces OR ddspaces) euclidean)) space~.
• Adding a wildcard symbol may retrieve word variants: information documentation a ((squared euclidean) or ((spaces or ddspaces) euclidean)) space*.
