Lucinq - A Fluent / Expressive API for SOLR, Azure Search and Lucene.NET

This project gives fluent style API to SOLR, Azure Search and Lucene. The primary purpose of which is to make the syntax a little less verbose whilst retaining the inherent power and speed of those tools.

Wiki

More complete documentation can be found in the wiki which can be found here: https://github.com/Code-Miners/Lucinq/wiki

Features

• A fluent style api for working with queries for most query types and groupings.
• Paging
• Sorting
• Query manipulation - remove terms and re-run for example.
• Collecting

Get it with NuGet

You can find the Nuget Package here: http://nuget.org/packages/Lucinq/

PM> Install-Package Lucinq

Example Syntax

Further examples can be found in the integration tests, however here is a quick overview of how the syntax looks

LuceneSearch search = new LuceneSearch(indexPath));

IQueryBuilder query = new QueryBuilder();

query.Term("field", "value");
query.Or
	(
		x => x.Term("_name", "work"),
		x => x.Term("_name", "text")
	);

LuceneSearchResult result = search.Execute(query.Build(), 20);	
foreach (Document document in result.GetTopDocuments())
{
	Console.WriteLine(document.GetValues("field")[0]);
}

OR

LuceneSearch search = new LuceneSearch(indexPath));

IQueryBuilder query = new IQueryBuilder();

query.Setup(
	x => x.Term("field", "value"),
	x => x.Or
			(
				y => y.Term("_name", "work"),
				y => y.Term("_name", "text")
			)
);

LuceneSearchResult results = search.Execute(query.Build(), 20);	
foreach (Document document in result.GetTopDocuments())
{
	Console.WriteLine(document.GetValues("field")[0]);
}

Further Projects

The intention at present is to allow the use of raw lucene with a view to writing overlays for Sitecore and potentially umbraco.
