问题描述
由于某种原因Lucene是不返回任何结果时，是应该的。这里是'搜索'code
For some reason lucene is not returning any results when it should be. Here is the 'search' code
Dim util As New IndexerUtil()
Dim dir As Lucene.Net.Store.Directory = FSDirectory.Open(New DirectoryInfo(util.getIndexDir()))
Dim indexSearcher As New IndexSearcher(dir, False)
Dim indexWriter As New IndexWriter(dir, New SimpleAnalyzer(), False, indexWriter.MaxFieldLength.UNLIMITED)
Dim term As New Term("id", "346")
Dim query As New TermQuery(term)
Dim topDocs As TopDocs = indexSearcher.Search(query, 100)
有没有scoreDocs（结果）的topDocs。我知道一个事实，那就是在该指数，其中id字段等于346但由于某种原因，搜索是没有找到它的文件。这里是如何的ID字段被创建
There are no scoreDocs (results) in topDocs. I know for a fact that there is a document in the index where the id field is equal to 346 however for some reason the search is not finding it. Here is how the "id" field is being created
doc.Add(New Field("id", ID, Field.Store.YES, Field.Index.ANALYZED)) //ID is an integer
我还有其他领域的搜索和那些做工精细（例如，如果我搜索关于这个问题的领域我得到的结果，我应该）
I have other fields to search on and those work fine (e.g. if I search on the subject field I get the results I should)
推荐答案
SimpleAnalyzer使用LetterTokenizer,只返回字母。
SimpleAnalyzer uses LetterTokenizer, which only returns letters.
考虑使用KeywordAnalyzer而不是为 ID 字段。
Consider using the KeywordAnalyzer instead for the id field.
