Is it possible to generate elasticsearch reports from indexed content?
问题 I'm just getting used to using elasticsearch in our platform, and so far it's proven to be a superb move, but other than some built in stats I haven't found any reference to creating a report of sorts. I guess the closest comparison would be facets, but it seems they need to be predefined in order to show stats for them. What I would like to know is, is it possible to run reports such as: What are the most popular phrases within the indexed content for the last 24 hours, week, etc.? This
