If I have a document with:
{ id: 1, sentences: "hello world|5.0_goodbye|2.3_this is a sentence|2.8" }How would I get those payloads to take affect, on the tokens separated by "_"? How do you write a query to use those payloads? On Wed, May 4, 2011 at 22:26, Otis Gospodnetic <otis_gospodne...@yahoo.com>wrote: > Hi Neil, > > I think payloads is the way to go.
