检索提示:

  • 检索的名词区分大小写
  • 常用字词将被忽略
  • 默认情况下只有在查询结果满足所有检索词才返回（例如，隐含AND）
  • 使用OR结合多个检索词，便于查找含有这些检索词的文章，例如education OR research
  • 使用括号来创建更复杂的查询; 例如：archive ((journal OR conference) NOT theses)
  • 使用引号检索一个完整的词组; 例如： "open access publishing"
  • 使用-或者NOT排除一个检索词; 例如：online -politics or online NOT politics
  • 在检索词里使用 *作为通配符匹配任何字符序列; 例如., soci* morality 将符合含有 "sociological" or "societal"的词语
