Talvez debería tentar con algunhas variantes ortográficas:
segmentation problem » segmentation problems, augmentation problem, augmentation problems
creating precision » creating decision, increasing precision, trading precision
creating precise » creating special, creating places
a penting » a penning, a penang, a pectin

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: segmentation problem ((creating precision) OR (creating precise)) a penting~.
• Adding a wildcard symbol may retrieve word variants: segmentation problem ((creating precision) or (creating precise)) a penting*.
