    <p>Here's a working example of Lucene.NET using a custom filter you might take a look at:</p> <pre><code>using System; using System.Collections; using Lucene.Net.Analysis; using Lucene.Net.Documents; using Lucene.Net.Index; using Lucene.Net.Search; using Lucene.Net.Store; class Program { static void Main(string[] args) { Directory index = new RAMDirectory(); Analyzer analyzer = new KeywordAnalyzer(); IndexWriter writer = new IndexWriter(index, analyzer, true); Document doc = new Document(); doc.Add(new Field("title", "t1", Field.Store.YES, Field.Index.TOKENIZED)); writer.AddDocument(doc); doc = new Document(); doc.Add(new Field("title", "t2", Field.Store.YES, Field.Index.TOKENIZED)); writer.AddDocument(doc); writer.Close(); Searcher searcher = new IndexSearcher(index); Query query = new MatchAllDocsQuery(); Filter filter = new LuceneCustomFilter(); Sort sort = new Sort("title", true); Hits hits = searcher.Search(query, filter, sort); IEnumerator hitsEnumerator = hits.Iterator(); while (hitsEnumerator.MoveNext()) { Hit hit = (Hit)hitsEnumerator.Current; Console.WriteLine(hit.GetDocument().GetField("title"). StringValue()); } } } public class LuceneCustomFilter : Filter { public override BitArray Bits(IndexReader indexReader) { BitArray bitarray = new BitArray(indexReader.MaxDoc()); int[] docs = new int[1]; int[] freq = new int[1]; TermDocs termDocs = indexReader.TermDocs( new Term(@"title", "t1")); int count = termDocs.Read(docs, freq); if (count == 1) { bitarray.Set(docs[0], true); } return bitarray; } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
