Bug Fix: binary OR with negation

Release Notes

Fixes #77 (incorrect query generated for expressions like d.Name != "x" || d.Year == 2010.

This query will now be generated as (*:* -Name:x) Year:2010 effectively allowing either clause to match. Previously this was generated as -Name:x Year:2010 effectively ANDing the clauses.

Parse queries without LINQ

Release Notes

This version provides two new methods on LuceneDataProvider:

• CreateQueryParser<T>() creates a Lucene QueryParser that knows how to create boolean queries with correct conversion and encoding of query values
• LuceneVersion and GetIndexedPropertyNames<T>() provide additional metadata about the binary format version of the index and which fields are indexed for a given document.

These new capabilities make it easier for your application to accept advanced queries as expressed as simple strings so queries can come from users or other code that isn't using LINQ to build them.

This version also fixes a bug when sorting results by a UnaryExpression as in the case of a property backed by a nullable value type.

Bug Fix: OData $skip and $select

Add support for aggressively flattening nested queries to allow query execution to work on queries generated by Web Api OData.

The following sample query would be produced by OData:

from ODataPackage <generated>_8 in {
  from SampleDocument p in value(Lucene.Net.Linq.LuceneQueryable`1[SampleDocument])
    orderby [p].Id asc, [p].Version asc select [p] => Skip(20)
  }
  select new SelectSome`1() {
    ModelID = "451afd8f-5957-4c03-99a5-8a81bf81a591",
    Container = new AutoSelectedNamedPropertyWithNext`1() {
      Name = "Version",
      Value = [<generated>_8].Version,
      Next = new NamedProperty`1() {
        Name = "Id",
        Value = [<generated>_8].Id
      }
    }
  } => Take(21)

These queries will now be flattened to remove the nesting.

Bug fix: dispose for realsies

Thanks to @igorkomsinus for reporting #70 - IndexReader not properly disposed.

Now Disposing LuceneDataProvider should release all handles to files in your index, allowing the index to be reopened, optimized or deleted.

Document Boost at Index Time

Thanks to Tamas Flamich (@tamasflamich) for providing mappings to boost documents when they are indexed.

See examples in Integration/DocumentBoostTests and fluent configuration in Fluent/DocumentBoostTests.

This release also makes sure the right version of Remotion.Linq gets installed when installing Lucene.Net.Linq and changes the dependency on Common.Logging to use the light PCL package Common.Logging.Core.

Query Statistics and more

New Features

• #23 Capture statistics on query execution
• #65 Fuzzy Match extension

Query Statistics

It is now possible to get the full count of hits when using Skip() and Take() to paginate:

LuceneQueryStatistics stats = null;

provider
  .AsQueryable<SampleDocument>()
  .CaptureStatistics(s => { stats = s; })
  .Where(d => d.SearchText == "foo")
  .Skip(20)
  .Take(20)
  .ToList();

See LuceneQueryStatistics.cs for available metadata.
