获取Lucene的Doc ID(Getting the Doc ID in Lucene)

获取Lucene的Doc ID(Getting the Doc ID in Lucene)

在lucene，我可以做以下事情

doc.GetField("mycustomfield").StringValue();

这将检索索引文档中列的值。

我的问题，对于同一个'doc' ，是否有办法获得Doc. Id Doc. Id ？ 卢克显示它，因此必须有办法解决这个问题。 我需要它删除更新文件。

我搜索了文档，但没有找到在GetField中使用的术语，或者是否已经有另一种方法。

In lucene, I can do the following

doc.GetField("mycustomfield").StringValue();

This retrieves the value of a column in an index's document.

My question, for the same 'doc', is there a way to get the Doc. Id ? Luke displays it hence there must be a way to figure this out. I need it to delete documents on updates.

I scoured the docs but have not found the term to use in GetField or if there already is another method.

最满意答案

事实证明你必须这样做：

var hits = searcher.Search(query); var result = hits.Id(0);

相反

var results = hits.Doc(i); var docid = results.<...> //there's nothing I could find there to do this

Turns out you have to do this:

var hits = searcher.Search(query); var result = hits.Id(0);

As opposed to

var results = hits.Doc(i); var docid = results.<...> //there's nothing I could find there to do this
