Is it possible to do a "tail" query on an index? (find the newest entries?)


(Steinar Bang) #1

Is it possible to do a "tail"-like query on an ES index? Ie. find the
newest entries, when I don't know the time stamp of the indexed items?

(It's actually the time stamp I'm looking for, as well as the actual
data indexed at that point in time)

Thanks!

You need to activate it in mapping: http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-timestamp-field.html#mapping-timestamp-field

Then you should be able to query and order by this field.
