To create an IndexWriter, an Analyzer is required. Each Document is actually a set of Fields and each field has a name and a textual value. The IndexWriter receives Documents as input, where documents are the unit of indexing and search. This will be done with the help of a class named IndexWriter, which is the class that creates and maintains an index. Next, setup a new Eclipse project, let’s say under the name “LuceneIntroProject” and make sure the aforementioned JAR is included in the project’s classpath.īefore we begin running search queries, we need to build an index, against which the queries will be executed. Also, make sure the Lucene API JavaDoc page is open at your browser (the docs are also included in the tarball for offline usage). Extract the tarball and locate the lucene-core-3.0.1.jar file which will be used later. tar.gz versions are significantly smaller than the corresponding.

The version I will use is 3.0.1 so I downloaded the lucene-3.0.1.tar.gz bundle (note that the.

The application we will build will allow you to index your own source code files and search for specific keywords.įirst things first, let’s download the latest stable version from one of the Apache Download Mirrors. Thus, I decided to provide some sample code to help you getting started with Lucene. I recently read a great tutorial about this project, but there was no actual code presented. NET port available under the name Lucene.NET, as well as several helpful sub-projects. I will deal with the Lucene Java version, but bear in mind that there is also a. Using its API, it is easy to implement full-text search. Lucene is an open-source project that provides Java-based indexing and search technology.

In this tutorial I would like to talk a bit about Apache Lucene.
