Perhaps you should try some spelling variations:
information segmentation » formation segmentation, information augmentation, information segregation
methods multidimensional » metric multidimensional, towards multidimensional, based multidimensional
segmentation methods » segmentation method, documentation methods
array fermi » array forming

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "information segmentation methods multidimensional ((array fermi) OR (array format))~".
• Adding a wildcard symbol may retrieve word variants: information segmentation methods multidimensional ((array fermi) OR (array format))*.
