This is my solution with Lucene Version.LUCENE_35. It is also called Lucene 3.5.0 from http://lucene.apache.org/java/docs/releases.html. If you are using an IDE like Eclipse, you can add the .jar file to your build path, this is the direct link to the 3.5.0.jar file: http://repo1.maven.org/maven2/org/apache/lucene/lucene-core/3.5.0/lucene-core-3.5.0.jar.

When a new version of Lucene comes out this solution will still be applicable ONLY if you continue using the 3.5.0.jar.

Now for the code:

import java.io.IOException;

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexReader;
import org.apache.lucene.index.IndexWriter;
import org.apache.lucene.index.IndexWriterConfig;
import org.apache.lucene.queryParser.ParseException;
import org.apache.lucene.queryParser.QueryParser;
import org.apache.lucene.search.IndexSearcher;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.ScoreDoc;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.RAMDirectory;
import org.apache.lucene.util.Version;

public class Index {
public static void main(String[] args) throws IOException, ParseException {
  // To store the Lucene index in RAM
    Directory directory = new RAMDirectory();
    // To store the Lucene index in your harddisk, you can use:
    //Directory directory = FSDirectory.open("/foo/bar/testindex");

    // Set the analyzer that you want to use for the task.
    Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_35);
    // Creating Lucene Index; note, the new version demands configurations.
    IndexWriterConfig config = new IndexWriterConfig(
            Version.LUCENE_35, analyzer);  
    IndexWriter writer = new IndexWriter(directory, config);
    // Note: There are other ways of initializing the IndexWriter.
    // (see http://lucene.apache.org/java/3_5_0/api/all/org/apache/lucene/index/IndexWriter.html)

    // The new version of Documents.add in Lucene requires a Field argument,
    //  and there are a few ways of calling the Field constructor.
    //  (see http://lucene.apache.org/java/3_5_0/api/core/org/apache/lucene/document/Field.html)
    // Here I just use one of the Field constructor that takes a String parameter.
    List docs = new ArrayList();
    Document doc1 = new Document();
    doc1.add(new Field("content", "Lucene in Action", 
        Field.Store.YES, Field.Index.ANALYZED));
    Document doc2 = new Document();
    doc2.add(new Field("content", "Lucene for Dummies", 
        Field.Store.YES, Field.Index.ANALYZED));
    Document doc3 = new Document();
    doc3.add(new Field("content", "Managing Gigabytes", 
        Field.Store.YES, Field.Index.ANALYZED));
    Document doc4 = new Document();
    doc4.add(new Field("content", "The Art of Lucene", 
        Field.Store.YES, Field.Index.ANALYZED));

    docs.add(doc1); docs.add(doc2); docs.add(doc3); docs.add(doc4);

    writer.addDocuments(docs);
    writer.close();

    // To enable query/search, we need to initialize 
    //  the IndexReader and IndexSearcher.
    // Note: The IndexSearcher in Lucene 3.5.0 takes an IndexReader parameter
    //  instead of a Directory parameter.
    IndexReader iRead = IndexReader.open(directory);
    IndexSearcher iSearch = new IndexSearcher(iRead);

    // Parse a simple query that searches for the word "lucene".
    // Note: you need to specify the fieldname for the query 
    // (in our case it is "content").
    QueryParser parser = new QueryParser(Version.LUCENE_35, "content", analyzer);
    Query query = parser.parse("lucene in");

    // Search the Index with the Query, with max 1000 results
    ScoreDoc[] hits = iSearch.search(query, 1000).scoreDocs;

    // Iterate through the search results
    for (int i=0; i
