Perhaps you should try some spelling variations:
computer programs » computer program (Expand search)
coder pathogen » canker pathogen (Expand search), coffee pathogen (Expand search), novel pathogen (Expand search)
pathogen based » pathogen and (Expand search), pathologies based (Expand search), pathogen barrier (Expand search)
based computer » based computing (Expand search), and computer (Expand search), board computer (Expand search)
using coupling » running coupling (Expand search), using competing (Expand search), using coupled (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: "(( coder pathogen based computer programs ) OR ( using coupling _ python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder pathogen based computer programs ) OR ( using coupling _ python programming ))*.
