A Systematic Literature Review of Automated Query Reformulations in Source Code Search [article]

Mohammad Masudur Rahman, Chanchal K. Roy
2021 arXiv   pre-print
Finally, we discuss several open issues in search query reformulations and suggest multiple future research opportunities.  ...  Then they execute the query with a code search engine (e.g., Lucene) and attempt to find out the exact locations within the software code that need to be changed.  ...  Hit@K determines whether there exists any ground truth within the top K results whereas recall determines the percentage of ground truth present in the top K results.  ...
