This is a beginner program in getting elsevier opensource papers.
2019ncov happened unexpectedly in Wuhan, China. This program is built for preserving some of 2019ncov correlated papers on Elsevier.
Crawling titles, abstracts, authors, keywords and doi from elsevier's opensource website, and building a database using Mirosoft Azure Cognitive Cloud Search. Also implementing some basic text analysis. 根据Elsevier开放数据库，爬取论文标题、摘要等信息，对其进行数据库的构造，并进行基础的文本分析。 Cautions: This program is kind of ineffective, and the crawling speed is still slow.
