Academic Search Engines: Constraints, Bugs, and Recommendation [PDF]

open access: yesarXiv, 2022
Background: Academic search engines (i.e., digital libraries and indexers) play an increasingly important role in systematic reviews however these engines do not seem to effectively support such reviews, e.g., researchers confront usability issues with the engines when conducting their searches.
