Perhaps you should try some spelling variations:
computations using » populations using (Expand search), computations in (Expand search), communications using (Expand search)
making method » making methods (Expand search), drying method (Expand search)
method python » method method (Expand search), python python (Expand search)
using making » using marking (Expand search), nursing making (Expand search), using ranking (Expand search)
pcr program » tpsr program (Expand search), ddr program (Expand search), r program (Expand search)

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

• Removing quotes may allow a broader search: (( AND computations using pcr program ) OR ( using making method python programming ))*.
