i have read this article Find trending article
Referring to Mark Harwood's comment on that page : " maybe it’s failing to find anything statistically significant in the sample of 100 headlines that differs materially from other days."
I had a follow-up question. Is it possible to run a "significant text" type aggregation without any background set ?
I want to find trending topics (i.e. unusual phrases) within a particular set of documents without any reference to any background set
how can this be done ?
