    <p>I am trying to implement simplest lucene search. I followed <a href="http://www.informit.com/articles/article.aspx?p=461633&amp;seqNum=2" rel="nofollow">this</a> as my starting point.</p> <p>I can understand the sample code :</p> <pre><code>public static void indexHotel(Hotel hotel) throws IOException { IndexWriter writer = (IndexWriter) getIndexWriter(false); Document doc = new Document(); doc.add(new Field("id", hotel.getId(), Field.Store.YES, Field.Index.NO)); doc.add(new Field("name", hotel.getName(), Field.Store.YES, Field.Index.TOKENIZED)); doc.add(new Field("city", hotel.getCity(), Field.Store.YES, Field.Index.UN_TOKENIZED)); doc.add(new Field("description", hotel.getDescription(), Field.Store.YES, Field.Index.TOKENIZED)); String fullSearchableText = hotel.getName() + " " + hotel.getCity() + " " + hotel.getDescription(); doc.add(new Field("content", fullSearchableText, Field.Store.NO, Field.Index.TOKENIZED)); writer.addDocument(doc); } </code></pre> <p>the thing i can't get in this code is what does <code>getIndexWriter(false)</code> do . this method is nowhere mentioned in the post i followed. moreover in another code block :</p> <pre><code>public void rebuildIndexes() throws IOException { // // Erase existing index // getIndexWriter(true); // // Index all hotel entries // Hotel[] hotels = HotelDatabase.getHotels(); for(Hotel hotel: hotels) { indexHotel(hotel); } // // Don’t forget to close the index writer when done // closeIndexWriter(); } </code></pre> <p>some undefined methods are used. </p> <p>A bit confusing for beginner like me.</p> <p>I want to create only one index . i think <code>getIndexWriter(true);</code> and <code>closeIndexWriter()</code> are some utility methods just to get <code>IndexWriter</code> but i can't make any assumption for what does that <code>true</code> in <code>getIndexWriter(true);</code> is used for.</p> <p>By following some other post's iv'e got more confused regarding the creation of IndexWriter.</p> <p>Can somebody please put me on the right path if i am doing anything wrong ?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
