HI One of use cases I have here deals with a sessions log where I have start\_time and end\_time of a session. It's easy to get sessions vis for all start\_time ones. How can I also have a query with Kibana which would include sessions with end\_time for the window requested with time picker? Is there a way to parse or inject the scope of time picker to build a query against two date-fields? Thanks! Marcin ---

What are you looking to gain insights into? If you are looking to visual the duration of the sessions over time, you could use a scripted field to calculate the difference between the end\_time and start\_time. ---

Hi @tsmalley Sorry for a silence from my side. Let me picture it out. ![](https://us1.discourse-cdn.com/elastic/original/2X/1/1f4afc83cbcd183c1d70850210e7baa286ecec5b.png) Arrows represent user sessions over time, and these sessions bear some statistic data, let's say Value\_X Sessions have `start_time` and `end_time`. Red vertical lines represent the analysis time window required. A - session started before the window and finished within window B - session started and ended within the window C - session started within the window and ended outside the window D - session started before the window and finished after the window Use case it to capture this with Kibana and do some ops on Value X - ie. sum value\_x ---
