Perhaps you should try some spelling variations:
"using computational foot example of" » "using computational cost example of" (Expand search), "using computational effort example of" (Expand search), "using computational blood example of" (Expand search), "using computational good example of" (Expand search), "using computational fit example of" (Expand search), "using computational first example of" (Expand search), "using computational foot sample of" (Expand search)
"and computational php computer program" » "_ computational php computer program" (Expand search), "and computational paths computer program" (Expand search), "and computational pain computer program" (Expand search), "and computational and computer program" (Expand search), "and computational ip computer program" (Expand search), "and computational _ 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: "((\"and computational php computer program\") OR (\"using computational foot example of\"))~".
• Removing quotes may allow a broader search: (( and computational php computer program ) OR ( using computational foot example of ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational php computer program") OR ("using computational foot example of"))*.
