Currently the database contents over 6.4million articles originating from over 80 countries of publication. Over 4,000 journals are currently on our list of which about 750 are abstracted completely, i.e. journals are taken cover to cover as a policy reflecting the fact that these journals almost without exception cover the core material of interest to the Database. That isn’t to say that other journals aren’t covered completely as they often are, but they will be chosen on a more individual basis. Over 2000 conferences, as well as many books, reports occasional publications and dissertations are scanned by Inspec staff for relevant articles to abstract and index for the database, and now over 330,000 articles are added each year. * * * * * * * 以下是一些额外的有关使用检索连接符的范例。 “AND”连接符检索含有所有所给词语的文档。此处所给的范例将检索含有短语“stem cell”以及词语“lymphoma”的数据。 当使用“OR”时，将检索至少含有一个所给关键字的数据。检索“Aspartame OR saccharine OR sweetener” 将得到包含所给的任何一个词语的数据。 “NOT”连接符被用来从您的检索中排除不需要的内容。检索“Aids NOT hearing” 将得到有关“AIDS（一种疾病）” 而不是“hearing aids（助听器）”。 * * 截词符，也叫“通配符”，可被用来检索复数形式及不同的词语拼写。在Web of Knowledge有三种不同的通配符。星号演示，是我在上面的检
