How to find the fields that are indexed?

Sir,

Am using lucene 2.3.2. I would like to know what are the fields that are been indexed?

Ex:

doc.get("path");

this statement returns the path of the document

like "path" what are the other fields of the document used by lucene

I went through converting all the class files to java files and read all the files. But i got confused with the things available in cluster.

So, Can anyone tell me how to find it out?

Thanks in advance,
Dhivya

Lucene will index and store the fields that you tell it to when a
document is written to the index.

In lucene 2.4 doc.getFields() returns a List of all the fields in a
document and probably in 2.3.2 as well. See the javadoc. That will
tell you the fields that have been stored but I think not necessarily
those that have been indexed i.e. made searchable.

Luke can tell you pretty much everything about an index.

Use this tool to examine the index: http://www.getopt.org/luke/

I would also suggest getting hold of a Lucene book such as Lucene In Action
(http://www.manning.com/hatcher2/) to get familiar with the basics of
Lucene.

Good.

There was something about it recently on this list. Take a look in
the archives. Or just google "lucene suggestions" or similar.

Re: How to find the fields that are indexed? [In reply to]

By autosuggest, would you mean similar documents?
In that case you could try the lucene 'morelikethis' class.
