Perhaps you should try some spelling variations:
techniques segmentation » techninques segmentation, techniques documentation, techniques instrumentation
segmentation a » segmentation _, segmentation based
scaler mode » scaled model, scales modes, safer mode
scale model » scale modeling
a curtan » a curran, _ curtain, _ cartan

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: ((scaler mode) OR (scale model)) techniques segmentation a curtan-metragem~.
• Adding a wildcard symbol may retrieve word variants: ((scaler mode) or (scale model)) techniques segmentation a curtan-metragem*.
