Perhaps you should try some spelling variations:
"advanced computation _ computing program" » "advanced computations _ computing program" (Expand search), "advanced computational _ computing program" (Expand search), "advance computational _ computing program" (Expand search), "advanced computation _ consulting program" (Expand search), "advanced computation _ computador program" (Expand search), "advanced computation _ computer programs" (Expand search)
"base compositional java computer program" » "base composition java computer program" (Expand search), "fase composicional java computer program" (Expand search), "and compositional java computer program" (Expand search), "base compositional data computer program" (Expand search), "base compositional and computer program" (Expand search), "base compositional hard 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: "((\"base compositional java computer program\") OR (\"advanced computation _ computing program\"))~".
• Removing quotes may allow a broader search: (( base compositional java computer program ) OR ( advanced computation _ computing program ))~.
• Adding a wildcard symbol may retrieve word variants: (("base compositional java computer program") OR ("advanced computation _ computing program"))*.
