Here is what i have written for you which works perfectly:

USE: queryParser.parse("\"Config migration from ASA5505 8.2 to ASA5516\"");

1. To create indexes

   public static void main(String[] args) 
   {
   
       IndexWriter writer = getIndexWriter();
       Document doc = new Document();
       Document doc1 = new Document();
       Document doc2 = new Document();
       doc.add(new Field("TITLE", "Config migration from ASA5505 8.2 to ASA5516",Field.Store.YES,Field.Index.ANALYZED));
       doc1.add(new Field("TITLE", "Firewall  migration from ASA5585 to ASA5555",Field.Store.YES,Field.Index.ANALYZED));
       doc2.add(new Field("TITLE", "Firewall  migration from ASA5585 to ASA5555",Field.Store.YES,Field.Index.ANALYZED));
       try 
       {
           writer.addDocument(doc);
           writer.addDocument(doc1);
           writer.addDocument(doc2);
           writer.close();
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
   }
   
   public static IndexWriter getIndexWriter()
   {
       IndexWriter indexWriter=null;
   
       try 
       {
       File file=new File("D://index//");
       if(!file.exists())
           file.mkdir();
       IndexWriterConfig conf=new IndexWriterConfig(Version.LUCENE_34, new StandardAnalyzer(Version.LUCENE_34));
       Directory directory=FSDirectory.open(file);
       indexWriter=new IndexWriter(directory, conf);
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       return indexWriter;
   }
   

   }

2.To search string

    public static void main(String[] args) 
    {

    IndexReader reader=getIndexReader();

    IndexSearcher searcher = new IndexSearcher(reader);

    QueryParser parser = new QueryParser(Version.LUCENE_34, "TITLE" ,new StandardAnalyzer(Version.LUCENE_34));

    Query query;
    try 
    {
    query = parser.parse("\"Config migration from ASA5505 8.2 to ASA5516\"");

    TopDocs hits = searcher.search(query,3);

    ScoreDoc[] document = hits.scoreDocs;
    int i=0;
    for(i=0;i
