Perhaps you should try some spelling variations:
context implementation » concept implementation, control implementation, context representation
implementation 1 » implementation 16, implementation 10, implementation 11
scale using » scale fishing, scale testing, cattle using
scar using » car using, sugar using, scans using
1 curtan » _ curtain, _ cartan, _ curtin

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: "((scar using) OR (scale using)) context implementation 1 curtan-metragem~".
• Adding a wildcard symbol may retrieve word variants: ((scar using) OR (scale using)) context implementation 1 curtan-metragem*.
