I had same kind of problem and I somehow managed to find a work around by initializing IndexSearcher from new reader. 

try {
			IndexReader newReader =  reader.reopen();
			if (newReader != reader) {
//			    reader was reopened
			   reader.close(); 
			   reader = null;
			 }

			reader = newReader;
			searcher = new IndexSearcher(newReader);
		} catch (Exception e) {
			e.printStackTrace();
		}
