在 lucene 中,我可以做到以下几点
In lucene, I can do the following
doc.GetField("mycustomfield").StringValue();
这会检索索引文档中列的值.
This retrieves the value of a column in an index's document.
我的问题,对于同一个'doc'
,有没有办法获取Doc.身份证
?卢克展示了它,因此必须有办法解决这个问题.我需要它来删除有关更新的文档.
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.
我搜索了文档,但没有找到要在 GetField 中使用的术语,或者是否已经有其他方法.
I scoured the docs but have not found the term to use in GetField or if there already is another method.
原来你必须这样做:
var hits = searcher.Search(query);
var result = hits.Id(0);
相对于
var results = hits.Doc(i);
var docid = results.<...> //there's nothing I could find there to do this
