More importantly, it means applications using Lucene.Net can coexist with applications using the Java version. First, it means someone familiar with Lucene’s Java implementation will have an easy time reading Lucene.Net’s C# code. This consistent port offers a number of advantages. It’s not only the classes and methods that are ported to C#, though the Lucene algorithms are ported too, as well as the Lucene index format. If you open any C# file and its corresponding Java file, you’ll see that, with the exception of the naming conventions, the class names and method names are the same-that is, .FSDirectory.createOutput( ) in Java becomes .CreateOutput( ) in C#. NET Framework, and it preserves the look and feel of Apache Lucene’s API. Lucene.Net is a port of Apache Lucene to C# that utilizes the Microsoft. Apache Lucene is written in Java, is well established as an ASF project, and has solid followers in the open source community. Lucene.Net’s origins can be traced back to its parent project, Apache Lucene. Indexing and searching via Lucene.Net’s APIs is easy and yet very powerful.
USING APACHE LUCENE CODE
You have to write the code to read from formats such as Microsoft Office files, extract the raw text out of the files, and pass this raw text data to Lucene.Net, where it can finally be indexed and later searched.Īfter your raw text data has been indexed, you can use Lucene.Net’s API to search this data. The task of extracting raw text data out of your binary data is your job.
All that Lucene.Net has to offer is a set of rich APIs that you must call to first create a Lucene.Net index and later search on that index. You must understand this about Lucene.Net so that you will be able to appreciate and understand its capabilities.
USING APACHE LUCENE PDF
Out of the box, Lucene.Net can’t extract or read your binary data (such as Microsoft Office or PDF files), make use of SQL data, or crawl the Web.
It can’t be used as-is out of the box to index and search your data or the Web. Lucene.Net is not a standalone search engine application. Now you have the power to bring the same indexing and searching capabilities into your applications using Lucene.Net, a high-performance, scalable search engine library written in the C# language and utilizing the. Google Desktop has made a splash by bringing this functionality to end users. Customers may want to be able to limit searches to certain keywords or to a particular set of data folders on a particular server, or to filter out information older than a particular date.
Furthermore, they will probably want to be able to exert some control over how searches are performed. That data often then gets scattered across a dizzying number of locations on different servers.Ĭhances are that your customers will need to deal with disparate data formats and with data stored in multiple locations. Businesses collect data in a staggering array of formats, including Microsoft Outlook or Excel files, Access or SQL databases, PDFs, HTML files, plain old text files, and perhaps even custom application formats. The challenge often isn’t in collecting and organizing your data but in finding it. Data is everywhere, whether it’s on the Internet, your local system, or networked hard drives.
