• Automatically converts PONOs to Documents and back
• Add, delete and update documents in atomic transaction
• Unit of Work pattern automatically tracks and flushes updated documents
• Update/replace documents with [Field(Key=true)] to prevent duplicates
• Term queries
• Prefix queries
• Range queries and numeric range queries
• Complex boolean queries
• Native pagination using Skip and Take
• Support storing and querying NumericField
• Automatically convert complex types for storing, querying and sorting
• Custom boost functions using IQueryable.Boost() extension method
• Sort by standard string, NumericField or any type that implements IComparable
• Sort by item.Score() extension method to sort by relevance
• Specify custom format for DateTime stored as strings
• Register cache-warming queries to be executed when IndexSearcher is being reloaded

First, create a plain old .net object that maps to your index. Use attributes to customize the field name and each field is stored and indexed. Quot Review Sheet

using System; using Lucene.Net.Linq.Mapping; public class Article { public string Author { get; set; } public string Title { get; set; } public DateTimeOffset PublishDate { get; set; } // Stores the field as a NumericField [NumericField] public long Id { get; set; } // Stores the field as text public int IssueNumber { get; set; } [Field(IndexMode.NotIndexed, Store = true)] public string BodyText { get; set; } // Maps to field "text" [Field("text", Store = false)] public string SearchText { get { return string.Join(" ", new[] { Author, Title, BodyText }); } } // Store complex type as string with a given TypeConverter [Field(Converter = typeof(VersionConverter))] public Version Version { get; set; } // Add IgnoreFieldAttribute to properties that should not be mapped to/from Document [IgnoreField] public string IgnoreMe { get; set; } } 

Next, create LuceneDataProvider and run some queries: Blog Examples Colourful

using System.Linq; using Lucene.Net.Analysis.Standard; using Lucene.Net.Index; using Lucene.Net.Linq; using Lucene.Net.Store; using Version = Lucene.Net.Util.Version; public class SampleProgram { public static void Main() { var directory = new RAMDirectory(); var writer = new IndexWriter(directory, new StandardAnalyzer(Version.LUCENE_29), IndexWriter.MaxFieldLength.UNLIMITED); var provider = new LuceneDataProvider(directory, writer.GetAnalyzer(), Version.LUCENE_29, writer); // add some documents using (var session = provider.OpenSession<Article>()) { session.Add(new Article { Author = "John Doe", BodyText = "some body text", PublishDate = DateTimeOffset.UtcNow }); } var articles = provider.AsQueryable<Article>(); var threshold = DateTimeOffset.UtcNow.Subtract(TimeSpan.FromDays(30)); var articlesByJohn = from a in articles where a.Author == "John Doe" && a.PublishDate > threshold orderby a.Title select a; var searchResults = from a in articles where a.SearchText == "some search query" select a; } } 

Environmental Monitoring Plan Template Use a PerFieldAnalyzerWrapper to control how queries and fields are analyzed. For the above example, fields like SearchText (text) should generally be analyzed using a stemming analyzer, but fields like Id, IssueNumber and Version should be indexed using a keyword analyzer.

• Ability to capture query statistics like execution time, total hits, top score, etc.
• Ability to use faceting to group results by field or natively return distinct field values
