您可以在检索词后包括检索字段标识来搜索特定字段中的检索词；例如，UCLA[ad]将仅在Affiliation（作者单位）中搜索“UCLA”一词。
有关使用检索字段标识的更多信息：
- 搜索字段标签必须用方括号[search field tags]括起来。
- 大小写和间距无关紧要：crabs [mh] = Crabs[mh]。
- 检索字段标识将关闭自动词汇映射（ATM），仅限制你输入的检索词。
- 在多个单词后使用检索字段标识将尝试将这些术语作为一个短语整体进行检索：kidney allograft[tiab]。
- 要在同一字段中搜索多个检索词，必须对每个检索词进行单独标记： covid-19[ti] vaccine[ti] children[ti]。
- 高级搜索构建器可以帮助您在特定字段中搜索检索词并构建大型复杂的检索表达式。
