I am new to lucene.net. I am developing an API to scan through the namelist. The Parameter will enter a full name of the person.

However with the current code, if i enter 'Pit Bull' search against the namelist, it will appear 'Pit Bull Adam', 'Pit Tim Bull' and etc...

But the result i want is 'Pit Bull' or 'Bull Pit' only.

Am i use the correct Analyzer or query? What should I do?

This is my index created.

        var doc = new Document();

        doc.Add(new Field("Id", model.EntityId.ToString(), Field.Store.YES, Field.Index.NOT_ANALYZED));

        doc.Add(new Field("FullName", model.FullName, Field.Store.YES, Field.Index.ANALYZED));

        doc.Add(new Field("Name2", model.Name2?? "", Field.Store.YES, Field.Index.ANALYZED));

        doc.Add(new Field("Name3", model.Name3?? "", Field.Store.YES, Field.Index.ANALYZED));

        doc.Add(new Field("Gender", indexModel.GenderType.HasValue ? indexModel.GenderType.Value.ToString() : "", Field.Store.YES, 

        Field.Index.NOT_ANALYZED, Field.TermVector.NO));

This is my search method.

using (var indexReader = IndexReader.Open(ramDirectory, true))

        {

            using (var searcher = new IndexSearcher(indexReader))

            {



                var analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_30);



                MultiFieldQueryParser _MultiMatchName = new 

                MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_30,

                    new string { "FullName", "Name2", "Name3" }, analyzer);



                const int hitLimits = 1000;



                _MultiMatchName.DefaultOperator = QueryParser.Operator.AND;



                var query = new BooleanQuery();



                query.Add(inputName,Occur.MUST);



            }

        }

It turned out i should use WhitespaceAnalyzer. When creating Index and searching index.

using (var indexReader = IndexReader.Open(ramDirectory, true))

    {

        using (var searcher = new IndexSearcher(indexReader))

        {



            var analyzer = new WhitespaceAnalyzer();



            MultiFieldQueryParser _MultiMatchName = new 

            MultiFieldQueryParser(Lucene.Net.Util.Version.LUCENE_30,

                new string { "FullName", "Name2", "Name3" }, analyzer);



            const int hitLimits = 1000;



            _MultiMatchName.DefaultOperator = QueryParser.Operator.AND;



            var query = new BooleanQuery();



            query.Add(inputName,Occur.MUST);



        }

    }
