Perhaps you should try some spelling variations:
communications using » communications in (Expand search), communications and (Expand search), communications plan (Expand search)
pulse program » purse program (Expand search), course program (Expand search), lease program (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
during lines » during linear (Expand search), during liver (Expand search), during live (Expand search)
lines python » in python (Expand search)
using pulse » using pulsed (Expand search), using pure (Expand search), using public (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 communications using pulse program ) OR ( during lines python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( AND communications using pulse program ) OR ( during lines python python programming ))*.
