Perhaps you should try some spelling variations:
"using compositional data coding program" » "using computational data coding program" (Expand search), "in compositional data coding program" (Expand search), "music compositional data coding program" (Expand search), "using compositional data cloning program" (Expand search), "using compositional data loading program" (Expand search), "using compositional data cooling programs" (Expand search), "using compositional data recording program" (Expand search), "using compositional data crossing program" (Expand search)
"using convolutional video coding program" » "using convolutional codes coding program" (Expand search), "using convolutional code coding program" (Expand search), "using conventional video coding program" (Expand search), "using convolutional video cloning program" (Expand search), "using convolutional video loading program" (Expand search), "using convolutional video cooling programs" (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: "((\"using compositional data coding program\") OR (\"using convolutional video coding program\"))~".
• Removing quotes may allow a broader search: (( using compositional data coding program ) OR ( using convolutional video coding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("using compositional data coding program") OR ("using convolutional video coding program"))*.
