[Liaqat Ali]

i m studying LIA. but there is a problem with code. When i run the code 
i get errorsThe errors are related with the use of deprecated 
APIs.Kindly suggest me the right APIs and also instructions how to 
handle this situation with other code..

package lia.indexing;

import org.apache.lucene.store.Directory;

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.SimpleAnalyzer;

   addDocuments(dir);
 }

   writer.setUseCompoundFile(isCompound());
   for (int i = 0; i < keywords.length; i++) {
     Document doc = new Document();
     doc.add(Field.Keyword("id", keywords[i]));
