This class is used to provide various constants to be used across the sample application. ![]() Next we will create LuceneTester.java and other java classes under the package. To do this, right-click on src in package explorer section and follow the option : New -> Package. First we need to create a package called. Applications usually need only call the inherited search (Query,int) method. Let us now create actual source files under the LuceneFirstApplication project. IndexSearcher (Lucene 8.8.1 API) Class IndexSearcher .IndexSearcher public class IndexSearcher extends Object Implements search over a single IndexReader. Now use Add External JARs button available under Libraries tab to add the following core JAR from the Lucene installation directory − To do this, right click on your project name LuceneFirstApplication and then follow the following option available in context menu: Build Path -> Configure Build Path to display the Java Build Path window as follows − ![]() Lucene Core is a Java library providing powerful indexing and search features, as well as spellchecking, hit highlighting and advanced analysis/tokenization. The project releases a core search library, named Lucene core, as well as PyLucene, a python binding for Lucene. Let us now add Lucene core Framework library in our project. The Apache Lucene project develops open-source search software. Once your project is created successfully, you will have following content in your Project Explorer − Step 2 - Add Required Libraries Now name your project as LuceneFirstApplication using the wizard window as follows − Follow the option File > New -> Project and finally select Java Project wizard from the wizard list. When implementing tokenization by using Lucene a problem related to .StandardAnalyzer occurred as the following exception was thrown: The import .StandardAnalyzer cannot be resolved I added dependencies to Maven pom.xml (see below) but the same exception was thrown again. The first step is to create a simple Java Project using Eclipse IDE. We'll also see the list of indexes created during this process. Let us now proceed by writing a simple Search Application which will print the number of search results found. It is recommended you have the working knowledge of Eclipse IDE. Before you start writing your first example using Lucene framework, you have to make sure that you have set up your Lucene environment properly as explained in Lucene - Environment Setup tutorial. In this chapter, we will learn the actual programming with Lucene Framework.
