Perhaps you should try some spelling variations:
"advanced modulation _ computing program" » "advanced calculation _ computing program" (Expand search), "advanced oxidation _ computing program" (Expand search), "advanced modulation _ consulting program" (Expand search), "advanced modulation _ computador program" (Expand search), "advanced modulation _ computer programs" (Expand search)
"engine optimization python computer program" » "engine optimization method computer program" (Expand search), "engine optimization option computer program" (Expand search), "engine optimization methods computer program" (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: "((\"advanced modulation _ computing program\") OR (\"engine optimization python computer program\"))~".
• Removing quotes may allow a broader search: (( advanced modulation _ computing program ) OR ( engine optimization python computer program ))~.
• Adding a wildcard symbol may retrieve word variants: (("advanced modulation _ computing program") OR ("engine optimization python computer program"))*.
