Perhaps you should try some spelling variations:
coder relationships » cover relationships (Expand search), border relationships (Expand search), modern relationships (Expand search)
extraction method » extraction methods (Expand search)
relationships on » relationships in (Expand search), relationships of (Expand search), relationships and (Expand search)
on extraction » green extraction (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
using api » using ai (Expand search), using app (Expand search), using aci (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 relationships on extraction method ) OR ( using api python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( coder relationships on extraction method ) OR ( using api python python programming ))*.
