Answer 1

To perform a Fuzzy search you'll create a MultiFieldQueryParser Below is an example on how to do this:

var parser = new MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_29, new[] { "field1", "field2" }, new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_29));

Your version of Lucene.Net may vary.

Next you will get a Fuzzy query from the parser like this:

var query = parser.GetFuzzyQuery("fieldName", "featured", 0.7f);

The float value of 0.7f is the minimum similarity. You can tweak this number until you get the desired results. The number cannot be more than 1.0f . Executing this query using an Lucene Searcher will give you the results you expect.

您可能正在寻找词干： 使用Lucene创建英语单词 - 链接是Java，但您应该能够识别lucene .Net API的相应部分。
