Question

我使用Lucene.NET3.0.3 如何获得TermAttribute.I尽我所能，但我无法得到它

这里来源：

    Analyzer analyzer = new Lucene.Net.Analysis.Snowball.SnowballAnalyzer(Lucene.Net.Util.Version.LUCENE_30, "English",stopword);

    TokenStream tokenStream = analyzer.TokenStream("English", new StringReader("How to get TermAttribute"));

    while (tokenStream.IncrementToken())
    {
         ???How to get TermAttribute

    }

Answer 1

var termAttr = tokenStream.GetAttribute<Lucene.Net.Analysis.Tokenattributes.ITermAttribute>();

while(tokenStream.IncrementToken())
{
    string term = termAttr.Term;
}

Answer 2

在Apache Lucene.Net 4.8中，您可以使用以下C＃代码：（。NET Core 2 +），其中<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/css/bootstrap.css"> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.1/js/bootstrap.min.js"></script> <div class="container"> <div class="row py-2"> <div class="col-sm-12"> <input type="search" id="myInput" placeholder="Start typing.." name="search" class="form-control searchbox-input" required=""> </div> </div> <div class="row"> <div class="col-sm-12"> <div class="row no-gutters bg-info"> <div class="col-sm-12 col-lg-4 p-3"> <h2>Day 1</h2> </div> <div class="col-sm-12 col-lg-8 p-3"> <h2>April 7, 2019</h2> </div> </div> <div class="card"> <div class="card-body"> <h4 class="card-title">Batman</h4> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.
