I set IndexSearcher as the application Object after the first search.

here is my code:

                             if(searcherOne.isOpen()==(true)){       
     
                                         Directory compressDir2 = 
                     
FSDirectory.getDirectory(compressionSourceDir02,false);
                                         IndexReader compressedSource2 =
IndexReader.open(compressDir2);
                                       Directory compressDir3 = 
                                            
FSDirectory.getDirectory(compressionSourceDir03,false);
                                         IndexReader compressedSource3 =
IndexReader.open(compressDir3);
                                         Directory compressDir4 = 
                                            
FSDirectory.getDirectory(compressionSourceDir04,false);
                                         IndexReader compressedSource4 =
IndexReader.open(compressDir4); 
                                        
          
                                         
        IndexReader[] readArray =
{compressedSource2,compressedSource3,compressedSource4};
        //merged reader
        IndexReader mergedReader = new MultiReader(readArray);
        IndexSearcher is = new IndexSearcher(mergedReader);
                                 BooleanQuery.setMaxClauseCount(1000000000);
        searcherOne.setIndexSearch(is);
                                         searcherOne.setOpen(false);
                                 BigInteger _l = new BigInteger(mobile1,
10);
                                 _mobile = _l.toString(36);
                                 QueryParser parser = 
                                     new QueryParser(AppConstants.CONTENTS,
new StandardAnalyzer());
                                 
                                 
                                searchQuery= 
                                       new
StringBuffer().append(_mobile).append(" AND dateSc:["
).append(fromDate).append(" TO ").append(toDate).append("]").append("
").append("AND").append(" ").append(callTyp).toString();
                                    
                                 
                                 
                                 
                                 Query callDetailquery =
parser.parse(searchQuery);
                                 
                                 hits = is.search(callDetailquery);
                                 System.out.println("FirstSearch");
                                 
                                 
                             }
      // System.out.println("No Of MAXIMUM dOCUMENTS : " +is.maxDoc());
      else{
          
       is=searcherOne.getIndexSearch();
      
        BigInteger _l = new BigInteger(mobile1, 10);
        _mobile = _l.toString(36);
   
        BooleanQuery.setMaxClauseCount(1000000000);
        QueryParser parser = 
            new QueryParser(AppConstants.CONTENTS, new StandardAnalyzer());
        
          searchQuery=new StringBuffer().append(_mobile).append("
").append(" AND dateSc:[" ).append(fromDate).append(" TO
").append(toDate).append("]").append(" ").append("AND").append("
").append(callTyp).toString(); 
         
              
           
       
        
        
         callDetailquery = parser.parse(searchQuery);
        
      hits = is.search(callDetailquery);
             

how can i reconstruct the new IndexSearcher for every hour to see the
updated records .
