I am looking for a SQL Server LAG/LEAD functions analog in Elasticsearch.
Assume I have a list of documents in result set found by particular criteria. The result set is also ordered in some order.
I know the id of one of the documents in that result set and I need to find next and/or previous document in the same result set.
SQL Server 2012 and above has LAG/LEAD functions to get next/previous row in the recordset. So I wondering if there is such functionality in the elasticsearch.
Could you please point me on the corresponding documentation/examples please?
There isn't. Lots of stuff from relational land doesn't translate directly into Elasticsearch land. What do you want to do with LAG/LEAD? Just getting the ids is simple enough by asking for more results and looking up or down the list. I imagine its something more fun but I don't want to speculate.
