是什么导致使用 Luke 的 Lucene 中出现“<field> indexed without position data”错误?

What causes "<field> indexed without position data" error in Lucene using Luke?

我正在尝试从使用 Lucene 索引的文档中搜索 DOI 字段。 DOI 的值类似于“10.1186/1756-3305-7-73”。请原谅,以防这个问题很愚蠢,但这是我第一次接触 Lucene。

错误是:

[2019-02-05 17:37:18,233] ERROR (ExceptionHandler.java:36) - field "doi" was indexed without position data; cannot run PhraseQuery (phrase=doi:"10.1186 s12937 015 0065 5") java.lang.IllegalStateException: field "doi" was indexed without position data; cannot run PhraseQuery (phrase=doi:"10.1186 s12937 015 0065 5")

问题详情:

不,我没看错。字段 "DOI" 的值已使用 Lucene 编制索引。

这是错误的完整日志:

我确实有一种直觉,这里的错误与解析查询表达式有关。我确实注意到 - 和 / 是从我的原始查询中解析出来的,但我不知道如何解决这个问题。任何方向都将不胜感激。

该死!经过一整天的努力,我找到了答案。

不能将标准分析器或简单分析器或英语分析器与唯一标识符类型查询一起使用。他们解析或修剪重要的关键字符号,例如连字符 and/or 正斜杠。

因此,我将关键字分析器 jars 导入 Luke 并使用它搜索查询表达式。

关键字分析器已从 here 下载并导入 Luke。
