Hi, I have a little doubt.

I'd like to tokenize a string. Something like this:

StandardAnalyzer analyzer = new StandardAnalyzer("hola mi nombre es Vicente");

List<string> tokens = analyzer.GetTokens();

And tokens is: [hola] [mi] [nombre] [es] [Vicente]

is this possible?

Thanks :)

            var analyzer = new StandardAnalyzer(Version.LUCENE_29);
             var textReader = new StringReader("hola mi nombre es Vicente");
             var tokenStream = analyzer.TokenStream("field", textReader);
             var terms = new List<String>();
             var termAttribute =
(TermAttribute)tokenStream.GetAttribute(typeof(TermAttribute));
             while(tokenStream.IncrementToken()) {
                 terms.Add(termAttribute.Term());
             }

             // terms = { "hola", "mi", "nombre", "es", "vicente" ]

Thank you very much, it works!!

But what is the meaning of "field"?

Thanks a lot :)

None in this example. The analyzer could be a PerFieldAnalyzerWrapper,
and the actual TokenStream retrieved would depend on the field
specified. The fieldName parameter is not used in
StandardAnalyzer.TokenStream, I could have passed null if I knew that
when I wrote the code.
