working sample code. Not organized in any specific order. Provided here to act as a scrap book for coding using the lucene api.

Given a unique key such as a URL, locate the document and return its term frequency vector.

public void printFieldNames() throws IOException
{
	Collection fieldNames = getReader().getFieldNames();
	Iterator itr = fieldNames.iterator();
	while(itr.hasNext())
	{
		Log.log((String)itr.next());
	}
}

An index reader has a getFieldNames() method. This will return an iterator of strings representing the field names.
