oh, I'm so sorry. you are right, I'm a newcommer! here I explained all
things I did!
I want to index some txt files in Lucene, for this means I copied a Index
Sourcecode, here is the code:
*
import* java.io.File;
*
import* java.io.FileReader;
*
import* java.io.IOException;
*
import* *org.apache.lucene.analysis.SimpleAnalyzer*;
*
import* org.apache.lucene.analysis.standard.StandardAnalyzer;
*
import* org.apache.lucene.document.Document;
*
import* org.apache.lucene.document.Field;
*
import* org.apache.lucene.index.IndexWriter;
*
import* *org.apache.lucene.store.Directory*;
*
import* org.apache.lucene.store.FSDirectory;
*
import* org.apache.lucene.store.RAMDirectory;
*
import* org.apache.lucene.util.Version;
*
public* *class* SimpleFileIndexer {
*public* *static* *void* main(String[] args) *throws* Exception {
File indexDir = *new* File("C:/Users/josh/documents");
File dataDir = *new* File("C:/Users/josh/index");
String suffix = "txt";
SimpleFileIndexer indexer = *new* SimpleFileIndexer();
*int* numIndex = indexer.index(indexDir, dataDir, suffix);
System.*out*.println("Total files indexed " + numIndex);
}
*private* *int* index(File indexDir, File dataDir, String suffix)
*throws*Exception {
RAMDirectory ramDir = *new* RAMDirectory();
IndexWriter indexWriter = *new* *IndexWriter(ramDir,
newStandardAnalyzer(Version.
LUCENE_33), true,
IndexWriter.MaxFieldLength.UNLIMITED)*;
indexWriter.*setUseCompoundFile(false)*;
indexDirectory(indexWriter, dataDir, suffix);
*int* numIndexed = indexWriter.maxDoc();
indexWriter.optimize();
indexWriter.close();
IndexWriter index = *new* *IndexWriter(FSDirectory.open(indexDir),
new StandardAnalyzer(Version.LUCENE_33), false,
IndexWriter.MaxFieldLength.UNLIMITED)*;
index.*addIndexesNoOptimize(ramDir)*;
index.optimize();
index.close();
*return* numIndexed;
}
*private* *void* indexDirectory(IndexWriter indexWriter, File dataDir,
String suffix) *throws* IOException {
File[] files = dataDir.listFiles();
*for* (*int* i = 0; i < files.length; i++) {
File f = files[i];
*if* (f.isDirectory()) {
indexDirectory(indexWriter, f, suffix);
}
*else* {
indexFileWithIndexWriter(indexWriter, f, suffix);
}
}
}
*private* *void* indexFileWithIndexWriter(IndexWriter indexWriter, File f,
String suffix) *throws* IOException {
*if* (f.isHidden() || f.isDirectory() || !f.canRead() || !f.exists()) {
*return*;
}
*if* (suffix!=*null* && !f.getName().endsWith(suffix)) {
*return*;
}
System.*out*.println("Indexing file " + f.getCanonicalPath());
Document doc = *new* Document();
doc.add(*new* Field("contents", *new* FileReader(f)));
doc.add(*new* Field("filename", f.getCanonicalPath(), Field.Store.*YES*,
Field.Index.*ANALYZED*));
indexWriter.addDocument(doc);
} }
then I added Lucene-core3.0.2 jar file but some functions and classes have
problem! (some parts with line in the code!!)
I have never worked with java before and all these are new for me, just I
want to run this code. I really need it, please help me and tell me which
steps I should do.
Thanks alot, and sorry for bad guidence once more.
