Awesome!  Thanks!

Or simpler:
wr = new IndexWriter(indexDir, aWrapper, !IndexReader.indexExists(indexDir));

This look better?

// Check to see if index exists. // If it doesn't, then set createIndex boolean to true

       boolean createIndex = false;
       if (!IndexReader.indexExists(indexDir)) {
           createIndex = true;
       }

       // let's set up the index writer
       wr = new IndexWriter(indexDir, aWrapper, createIndex);
       wr.setUseCompoundFile(false);

I think you can reuse them.  Fields should he handled/analyzed sequentially.  I 
reuse them for some stuff on Simpy.com.

But you may want to clean up that try/catch.  Instead of catching the 
IOException, you may want to use !IndexReader.indexExists(...) in place of that 
boolean param to IndexWriter ctor.

Hey Erik,

Will do.  May I ask why?  Out of curiousity.

Thanks,
Michael

I think you should use a new instance of each analyzer for each field, not reuse instances. Other than that, your usage is fine.

So I have the following code...

// let's get our SynonymAnalyzer
SynonymAnalyzer synAnalyzer = getSynonymAnalyzer();
// let's get our EmailAnalyzer
EmailAnalyzer emailAnalyzer = getEmailAnalyzer();

// set up perfieldanalyzer

PerFieldAnalyzerWrapper aWrapper = new PerFieldAnalyzerWrapper(new StandardAnalyzer()); aWrapper.addAnalyzer("subject", synAnalyzer);

aWrapper.addAnalyzer("content", synAnalyzer);
aWrapper.addAnalyzer("from", emailAnalyzer);
aWrapper.addAnalyzer("to", emailAnalyzer);
aWrapper.addAnalyzer("cc", emailAnalyzer);
aWrapper.addAnalyzer("bcc", emailAnalyzer);

// create the writer
try {
 wr = new IndexWriter(indexDir, aWrapper, false);
 wr.setUseCompoundFile(false);
} catch (IOException iox) {
 // means it ain't there
 wr = new IndexWriter(indexDir, aWrapper, true);
 wr.setUseCompoundFile(false);
}

When I add a Document to the IndexWriter it does not seem to use the analyzer's I want it too. Just uses StandardAnalyzer for everythign! Is this the correct way to use PerFieldAnalyzerWrapper?

Thanks,
Michael

P.S.  I am using Lucene 2 libs.
