如何搜索确切的短语？

Question

I want to search an exact phrase in Lucene .

I am using the below code:

public void AddSearchString(string searchString)
{
    MultiFieldQueryParser parser = new MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_30, ELRNLessonDocument.SearchableFields.ToArray(), new ELRNAnalyzer(Lucene.Net.Util.Version.LUCENE_30));
    parser.DefaultOperator = QueryParser.Operator.AND;
    parser.PhraseSlop = 0;
    Query.Add(parser.Parse(searchString), Occur.MUST);
}

But it doesn't support exact word searches, like: 'Climate Change'. The result must show the exact combination of the text. How can I solve this issue?

使用短语查询 ，将其用引号引起来：

parser.Parse("\"" + searchString + "\"");
