Perhaps you should try some spelling variations:
"using combinational logic coding program" » "using combination logic coding program" (Expand search), "using combinations logic coding program" (Expand search), "using computational logic coding program" (Expand search), "using combinational logic cloning program" (Expand search), "using combinational logic loading program" (Expand search), "using combinational logic cooling programs" (Expand search), "using combinational logic modeling program" (Expand search), "using combinational logic using program" (Expand search)
"using complex data coding program" » "using complex data cloning program" (Expand search), "using complex data loading program" (Expand search), "using complex data cooling programs" (Expand search), "housing complex data coding program" (Expand search), "using computer data coding program" (Expand search), "using complex data recording program" (Expand search), "using complex data crossing program" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("using combinational logic coding program") OR ("using complex data coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"using combinational logic coding program\") OR (\"using complex data coding program\"))".
• Removing quotes may allow a broader search: (( using combinational logic coding program ) OR ( using complex data coding program )).
• Adding a wildcard symbol may retrieve word variants: (("using combinational logic coding program") OR ("using complex data coding program"))*.
