Perhaps you should try some spelling variations:
"coder model computational study protocol" » "coder models computational study protocol" (Expand search), "coder modelo computacional study protocol" (Expand search), "coder code computational study protocol" (Expand search), "cover model computational study protocol" (Expand search), "decoder model computational study protocol" (Expand search), "copper model computational study protocol" (Expand search)
"api python python python programming" » "api pythons python python programming" (Expand search), "api piton python python programming" (Expand search), "api pitons python python programming" (Expand search), "rpa python python python programming" (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 model computational study protocol\") OR (\"api python python python programming\"))~".
• Removing quotes may allow a broader search: (( coder model computational study protocol ) OR ( api python python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder model computational study protocol") OR ("api python python python programming"))*.
