Hi there, We want to do more with the data we're indexing, so that we can do some real-time anomaly detection. We've been looking at the percolator feature as a simple starting point, but I just want to get an idea of if what I'm asking is possible. We want a stored query that will match when a document comes through, and is e.g. "the 10th delete request performed by user Foo in the last two days!". For documents like {user: "foo", action: "delete", object: "deletedthing"}. Can Percolator queries do that - look at more than just the document coming through? Is there a good example or tutorial around that? Should we be looking at something else for this kind of data analysis?
