What is Lucene4DB.Net?

Lucene4DB.Net is a .Net library built around the powerful Lucene search engine to index database tables and allow fast and advanced search capability to your applications. Now you do not have to spend hours thinking during designing of the schema about the fields that you should index. Lucene4DB.Net makes it possible to pick and drop the fields at run time. One would argue that database applications like Microsoft SQL Server, MySQL, Oracle and others have indexing capabilities then why should you build a new index. There are number of reasons why using a tool like Lucene4DB.Net can boost search for your applications, desktop or web.

• Fast and flexible indexing of terabytes of data in your database.
• Gives ability to add fast and accurate search capabilities to your applications.
• Supports free form search queries with accurate results.
• Frees you from worries of SQL injection attacks.
• A very simple and intutive API to add tables and columns to the index.
• Ability to add or modify indexed fields at run time. You do not have to modify the schema of your database to include or exclude fields that need to be indexed.
• Hot addition of new records at run time allows incremental build of index. And supports ability to remove records from index.
• Ability to crate and move the index files from one location to other. This gives you ability to use the same index for multiple applications.

Do I need to know SQL to create query?

No you do not need to know who to build queries or things like that. We provide a very simple and intutive and simple API that lets you add fields, tables, joins, conditions etc. like you are setting properties on a bussiness object and our query builder will take care of the rest for you.

What version of .Net Framework is supported?

The API supports .Net 1.1 and .Net V2.0. There is a special build for .Net 2.0 which leverages new features of the framework.
