使用 C# 的 Lucene 搜索词

Question

I implemented searching with Lucene as code below

  var fields = new[] { "Locality", "SubLocality", "Administrative_level_1", "Administrative_level_2", "Administrative_level_3" };    
               var queryParser = new MultiFieldQueryParser(Version.LUCENE_30, fields, analyzer);             
               var query = queryParser.Parse(searchQuery);
               var hits = searcher.Search
                (query, null, hits_limit, Sort.RELEVANCE).ScoreDocs;
                var results = _mapLuceneToDataList(hits, searcher);
                analyzer.Close();
                searcher.Dispose();
                return results;

If i put the key word like "Eastern Cape",it is also displaying result for "Western Cape".

How can i only get result searching for "Eastern Cape"?

您需要设置使用精确搜索的可能性，这是通过在您的 queryBuilder 中从您的 searchquerystring 中创建一个短语查询来完成的。
