I've opened the index with Luke and the index are good.

My code that use Multisearcher:

this line I don't know what it do, but i think that is not the problem
private int[] required= 
{MultiFieldQueryParser.NORMAL_FIELD,MultiFieldQueryParser.NORMAL_FIELD,MultiFieldQueryParser.NORMAL_FIELD};
private IndexSearcher[] searchers;
       
//indexs have the path of my indexs Lucene

       for (int i = 0; i < indexs.length; i++) {
            searchers[i] = new IndexSearcher(getPath(indexs[i]));
       }
        searcher = new MultiSearcher(searchers);
        MultiSearcher searcher=iService.openMultiSearcher();
        SearchResults sr=null;
            Query buscar = 
MultiFieldQueryParser.parse(search_text,fields,required,analyzer);
            Hits encontrados=searcher.search(buscar);
            sr = new SearchResults(encontrados,userviewer,idPortal);
        searcher.close();
