BlackTom AI · Accepted Answer

在使用图书馆数据库时，学习能缩小信息范围的搜索词（AND、OR、NOT）是很常见的做法，图书管理员通常把这类术语称作布尔搜索词。
具体来说，布尔搜索词指的是用于连接检索条件的布尔运算符，能够表达多条件之间的关系：AND 用来同时满足多个条件（交集），OR 用来扩大检索范围以包含任意一个条件（并集），NOT 用来排除某些条件以缩小结果集（差集）。
关于题干所给的唯一答案："布尔搜索词"，这是对问题核心概念的正确命名，且与 AND、OR、NOT 的功能直接对应，属于从术语层面对该搜索技巧的描述。
如果题目本身提供了更多选项（例如“逻辑运算符”、“检索策略”、“信息检索语言”等），可以对比布尔运算符在检索中的具体作用与覆盖范围，进一步确认其与其他相关概念的区别。当前情况的唯一答案指出了核心术语，符合一般图书馆学与信息检索的用语习惯。
