Re: [Katta-developer] retrieving lucene document details best possible approach in Katta

[Xiaomeng W. <sha...@gm...>]

I use this to retrieve a field containing int values.

Integer.parseInt(client.getDetails(hit,field).values().toArray()[0].toString());

It should be better since it doesnot fetch again.

Xiaomeng
