Description

Right now i am using below code to search.

MultiFieldQueryParser multiParser = new MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_30,
new[]

{ "EntityName", "EntityDesc", "EntityTranscript", "CourseSystemID", "Tags", "Objectives" }

,
new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_30));

if (searchTerm.Contains("\""))

{ multiParser.DefaultOperator = QueryParser.Operator.AND; }

else

{ multiParser.DefaultOperator = QueryParser.Operator.OR; }

string parserTerm = ReplaceSpecialCharactersInSearchTerm(searchTerm);
searchResults.Clear();

// parse the query
Query query = multiParser.Parse(parserTerm);
TopDocs results = searcher.Search(query, 20000);

Above code is working fine form , but if i give "Dynamcis 365 Enterprise" as search keyword it is bring resutls for each and every work match like , Dynamics word ,365 word match and Enterprise match. But my requirement is exact string("Dynamcis 365 Enterprise") match.
To achieve this i have changed my code from parser to phrase query. But it is giving ScoreDocs count Zero.

Please hlep me on this how to achieve.
