我開始學習Lucene,所以我正在閱讀Lucene in Action。從這本書中關於場的摘錄:Lucene - 關鍵字提交混淆
Keyword—Isn’t analyzed, but is indexed and stored in the index verbatim.
This type is suitable for fields whose original value should be preserved in
its entirety, such as URLs, file system paths, dates, personal names, Social
Security numbers, telephone numbers, and so on
我從這個理解是什麼,如果一個文本與關鍵字字段它不分析索引(不分割成tokens),但被索引。但是,我不明白的是and stored in the index verbatim
。
我對存儲在索引中感到困惑。我認爲如果文本被編入索引,它將被存儲在索引數據結構中。
任何人都可以用一個例子來解釋我嗎?
