A Literature Review of Indexing and Searching Techniques Implementation in Educational Search Engines

摘要

>The objective of this article is to analyze the searching and indexing techniques of educational search engine's implementation while treating future challenges. Educational search engines could greatly help in the effectiveness of e-learning if used correctly. However, these engines have several gaps which influence the performance of e-learning actors (students, teachers, administration, and other stakeholders) which requires more attention. In education environments, the implementation of e-learning systems seems to be among the important topics on the agenda of universities. Considering the arduous research, the extensive pedagogical development and the large financial support, expectations for positive results are incredibly high. However, e-learning actors step back and think about the educational search engines that are part of e-learning systems; and reflect on what the different indexing and searching techniques are used by these search engines.
