Subject RE: NumericRange Field and LuceneUtils?
Date Fri, 11 Sep 2009 20:37:56 GMT
Hallo Daniel,

I am not really sure what you are talking about (what is LuceneUtils?).

To your question about NumericField: NumericField is only used for indexing.
If you also store the field to retrieve it from the index e.g. with search
results, NumericField creates a stored Field containing the number as a
conventional string (the special trie encoding is only used for *indexing*
not *storing*). If you call getField() it returns a standard Field containg
the number as String.
