The main objective of this work is to analyse the contributions of Judit Bar-Ilan to the search engines studies. To do this, two complementary approaches have been carried out. First, a systematic literature review of 47 publications authored and co-authored by Judit and devoted to this topic. Second, an interdisciplinarity analysis based on the cited references (publications cited by Judit) and citing documents (publications that cite Judit's work) through Scopus. The systematic literature review unravels an immense amount of search engines studied (43) and indicators measured (especially technical precision, overlap and fluctuation over time). In addition to this, an evolution over the years is detected from descriptive statistical studies towards empirical user studies, with a mixture of quantitative and qualitative methods. Otherwise, the interdisciplinary analysis evidences that a significant portion of Judit's oeuvre was intellectually founded on the computer sciences, achieving a significant, but not exclusively, impact on library and information sciences.

跨越学术海洋？Judit Bar-Ilan 关于搜索引擎研究的全部作品

这项工作的主要目的是分析 Judit Bar-Ilan 对搜索引擎研究的贡献。为此，采取了两种互补的方法。首先，对由 Judit 撰写和合着并致力于该主题的 47 篇出版物的系统文献综述。其次，基于引用的参考文献（Judit 引用的出版物）和引用文件（引用 Judit 作品的出版物）通过 Scopus 进行跨学科分析。系统的文献综述揭示了大量研究的搜索引擎 (43) 和衡量的指标（特别是技术精度、重叠和随时间的波动）。除此之外，从描述性统计研究到经验性用户研究，结合定量和定性方法，发现了多年来的演变。除此以外，
