lucene.net语音过滤器 [英] lucene.net phonetic filter

问题描述

我正在尝试将文本数据存储到lucene.

I am trying to store text data to lucene.

搜索应带有语音！

我应该在哪里添加语音过滤器?

Where should I add a phonetic filter?

Lucene.Net.Store.Directory dir =
FSDirectory.Open(new DirectoryInfo(Application.StartupPath + "\\Index"));

IndexReader indexReader = IndexReader.Open(dir, true);
Searcher indexSearch = new IndexSearcher(indexReader);
//IndexReader indexReader = IndexReader.Open(dir, true);
//Searcher indexSearch = new IndexSearcher(indexReader);
Analyzer analyzer = new Lucene.Net.Analysis.De.GermanAnalyzer();

//Analyzer analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_29);
var queryParser = new QueryParser(Lucene.Net.Util.Version.LUCENE_29,"content", analyzer);
var query = queryParser.Parse(textBox1.Text+"~0.8");

Console.WriteLine("Searching for: " + query.ToString());
TopDocs resultDocs = indexSearch.Search(query, indexReader.MaxDoc());

Console.WriteLine("Results Found: " + resultDocs.TotalHits)

关于Ingo，

推荐答案

一种方法是实现将Analyzer添加到TokenStream链中的Analyzer，或直接使用TokenStream.

One way is to implement an Analyzer that adds it to the TokenStream chain, or use a TokenStream directly.

即:

System.IO.TextReader someText = ....;
TokenStream phonetics = new PhoneticFilter(new LowerCaseFilter(new WhitespaceTokenizer(someText )));

用实现的TokenFilter替换PhoneticFilter，并在搜索和索引时都使用它.

Replace PhoneticFilter with the TokenFilter you implemented, and use this both at search and index time.
