An important note:
As we were preparing the manuscript, several tools kept changing their features and new tools were reported frequently. After some time, we had to stop following up the changes. This shows the flux in the literature search domain. The corresponding author is also developing a new tool to aid very specific aspects of citation retrieval from PubMed!|

Tools not considered in the current study: We have taken up a large number of search engines for comparative study. However, we were unable to access or use several of these programs due to:
- lack of proper user guide,
- they were too slow to respond or
- required subscription. Except Scopus, which was providing free trial access earlier, we were unable to use the other paid programs (Web of Science, Ovid, NextBio and Scifinder). Similarly, we also could not incorporate some of the relatively new ones (SUMSearch and Novo|seek) in the current analyses. Some tools were non-functional on some of the occasions we tried to access, and hence left out.
