Perhaps you should try some spelling variations:
"code computation in coverage of" » "core computation in coverage of" (Expand search), "code computational in coverage of" (Expand search), "pose computation in coverage of" (Expand search), "code computation and coverage of" (Expand search), "code computation of coverage of" (Expand search), "code imputation in coverage of" (Expand search)
"using in python python programming" » "using in pythons python programming" (Expand search), "using in piton python programming" (Expand search), "using in pitons python programming" (Expand search), "using _ python python programming" (Expand search)

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: "((\"code computation in coverage of\") OR (\"using in python python programming\"))~".
• Removing quotes may allow a broader search: (( code computation in coverage of ) OR ( using in python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("code computation in coverage of") OR ("using in python python programming"))*.
