问题
I am trying to store text data to lucene.
The search should be with phonetic!
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)
Regards, Ingo
回答1:
One way is to implement an Analyzer
that adds it to the TokenStream
chain, or use a TokenStream directly.
ie:
System.IO.TextReader someText = ....;
TokenStream phonetics = new PhoneticFilter(new LowerCaseFilter(new WhitespaceTokenizer(someText )));
Replace PhoneticFilter
with the TokenFilter
you implemented, and use this both at search and index time.
