Retrieving field names from an index

[Stadler Hans-Christian <ha...@psi.ch>]

Hi,

how would I efficently retrieve the names of all possible fields present in an index?

One way would be to iterate over all terms and extract the field names, but it doesn't
look like this method is efficient for large indices.

Hi
you can get them from searcher, if documents in your index are the same

Enumeration fields = searcher.doc(0).fields();

Would IndexReader.getFieldNames work?
