我正在使用包含谓词在 SQL Server 索引文本字段中查找短语。有没有办法返回包含搜索短语的文本字段部分,或者它周围的某个区域?
例如,如果我在葛底斯堡演说中搜索“人人生而平等”(摘录如下),我想返回“致力于人人生而平等的命题”,例如围绕它的一些文本。
Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that *all men are created equal.*
Now we are engaged in a great civil war, testing whether that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.
