# Interoperating with Java Lucene # File Formats Zend_Search_Lucene index file formats are binary compatible with Java Lucene version 1.4 and greater. A detailed description of this format is available here: `http://lucene.apache.org/java/2_3_0/fileformats.html` [1] . # Index Directory After index creation, the index directory will contain several files: The segments file is a list of index segments. The *.cfs files contain index segments. Note! An optimized index always has only one segment. The deletable file is a list of files that are no longer used by the index, but which could not be deleted. # Java Source Code The Java program listing below provides an example of how to index a file using Java Lucene: /** * Index creation: */ import org.apache.lucene.index.IndexWriter; import org.apache.lucene.document.*; import java.io.* ... IndexWriter indexWriter = new IndexWriter("/data/my_index", new SimpleAnalyzer(), true); ... String filename = "/path/to/file-to-index.txt" File f = new File(filename); Document doc = new Document(); doc.add(Field.Text("path", filename)); doc.add(Field.Keyword("modified",DateField.timeToString(f.lastModified()))); doc.add(Field.Text("author", "unknown")); FileInputStream is = new FileInputStream(f); Reader reader = new BufferedReader(new InputStreamReader(is)); doc.add(Field.Text("contents", reader)); indexWriter.addDocument(doc); [1] The currently supported Lucene index file format version is 2.3 (starting from Zend Framework 1.6).
