Perhaps you should try some spelling variations:
"coder modeling using linear complexity" » "coder modeling using lower complexity" (Expand search), "coder modeling using higher complexity" (Expand search), "cover modeling using linear complexity" (Expand search), "cover modelling using linear complexity" (Expand search), "order modeling using linear complexity" (Expand search), "coder model using linear complexity" (Expand search), "coder models using linear complexity" (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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coder modeling using linear complexity") OR ("api python python python programming"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coder modeling using linear complexity\") OR (\"api python python python programming\"))".
• Removing quotes may allow a broader search: (( coder modeling using linear complexity ) OR ( api python python python programming )).
• Adding a wildcard symbol may retrieve word variants: (("coder modeling using linear complexity") OR ("api python python python programming"))*.
