    <p>Consider following assumptions:</p> <ol> <li>I have Java 5.0 Web Application for which I'm considering to use Lucene 3.0 for full-text searching </li> <li>There will be more than 1000K Lucene documents, each with 100 words (average)</li> <li>New documents must be searchable just after they are created (real time search)</li> <li>Lucene documents have frequently updating integer field named quality</li> </ol> <p>Where to find code examples (simple but as complete as possible) of near real time search of Lucene 3.0?</p> <p>Is it possible to obtain query results sorted by one of document fields (quality) which may be updated frequently (for already indexed document)? Such updating of document field will have to trigger Lucene index rebuilding? What is performance of such rebuilding? How to done it efficiently - I need some examples / documentation of complete solution.</p> <p>If, however, index rebuilding is not necessarily needed in this case - how to sort search results efficiently? There may be queries returning lots of documents (>50K), so I consider it unefficient to obtain them unsorted from Lucene and then sort them by quality field and finally divide sorted list to pages for pagination.</p> <p>Is Lucene 3.0 my best choice within Java or should I consider some other frameworks/solutions? Maybe full text search provided by SQL Server itself (I'm using PostgreSQL 8.3)?</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.
