Fusion of indicators by typical strategies: All the typical strategies have considered the frequency-based indicator (TF). However, CCSEe and eGRABe, which fuse TF and locality-based indicators, even deteriorates performance (TF has been able to achieve a higher MAP of 0.6633, ref. Fig. 1). BM25e and TFIDF, which fuse TF and the rareness-based indicator IDF, can further improve performance. TFIDF performs significantly better than others in Average P@1 and P@2 (‘•’ denotes that the indicator performs significantly better than others). ESe fuses TF, IDF, and the concentration-based indicator (AvgTF). It performs significantly better than others in Average P@3 and MAP
