Re: How to get all field names

I will volunteer. It might take me a bit of time as I'm not familiar with that part of the code yet.

This would not be hard to implement.

It would take something like:

public abstract String[] IndexReader.getFieldNames();

This would need to be implemented in two classes, SegmentReader and SegmentsReader. The former would just access its fieldInfos field to list fields. The latter would iterate through its readers field, collecting all of the field names, and finally return them as an array.

Would someone like to contribute diffs for this?

Yes, but it seems there is no such enumerator for a complete index.

Hi,

I was wondering if there is a possibility to get a list of all field names
that have ever been used to index a document? This way I could filter out
some special fields, like identity and such, and do a search over the
remaining. That would give me total freedom to choose any document
structure and have all fields searched. Is this possible? Or do anyone of
you have a better way achieving that?

Regards
Christoph
